اِلٰہِ النَّاسِ سورة النَّاس114:4 The God of mankind

وَہُوَ الَّذِیۡ فِی السَّمَآءِ اِلٰہٌ وَّفِی الۡاَرۡضِ اِلٰہٌ ۚ وَہُوَ الۡحَکِیۡمُ الۡعَلِیۡمُ سورة الزّخرُف43:85 And He it is Who is God in heaven, and God on earth; and He is the Wise, the All-Knowing.

اَللّٰہُ لَاۤ اِلٰہَ اِلَّا ہُوَ ۖ لَہُ الۡاَسۡمَآءُ الۡحُسۡنٰی سورة طٰه20:9 Allah — there is no God but He. His are the most beautiful names.

وَاِلٰہُکُمۡ اِلٰہٌ وّٰحِدٌ ۖ لَّاۤ اِلٰہَ اِلَّا ہُوَ الرَّحۡمٰنُ الرَّحِیۡمُ سورة البَقَرَة2:164 And your God is One God; there is no God but He, the Gracious, the Merciful.

اَمۡ لَہُمۡ اِلٰہٌ غَیۡرُ اللّٰہِ ۚ سُبۡحٰنَ اللّٰہِ عَمَّا یُشۡرِکُوۡنَ سورة الطُّور52:44 Have they a God other than Allah? Exalted is Allah above all that which they associate with Him!

مَا اتَّخَذَ اللّٰہُ مِنۡ وَّلَدٍ وَّمَا کَانَ مَعَہٗ مِنۡ اِلٰہٍ ۚ اِذًا لَّذَہَبَ کُلُّ اِلٰہٍۭ بِمَا خَلَقَ وَلَعَلَا بَعۡضُہُمۡ عَلٰی بَعۡضٍ ۚ سُبۡحٰنَ اللّٰہِ عَمَّا یَصِفُوۡنَ سورة المؤمنون23:92 Allah has not taken unto Himself any son, nor is there any other God along with Him; in that case each god would have taken away what he had created, and some of them would surely have dominated over others. Glorified be Allah above all that which they attribute to Him!

اِنَّہُمۡ کَانُوۡۤا اِذَا قِیۡلَ لَہُمۡ لَاۤ اِلٰہَ اِلَّا اللّٰہُ یَسۡتَکۡبِرُوۡنَ سورة الصَّافات37:36 For when it was said to them, There is no God but Allah,’ they turned away with disdain,

شَہِدَ اللّٰہُ اَنَّہٗ لَاۤ اِلٰہَ اِلَّا ہُوَ وَالۡمَلٰٓئِکَۃُ وَاُولُوا الۡعِلۡمِ قَآئِمًۢا بِالۡقِسۡطِ ۚ لَاۤ اِلٰہَ اِلَّا ہُوَ الۡعَزِیۡزُ الۡحَکِیۡمُ سورة آل عِمرَان3:19 Allah bears witness that there is no God but He — and also do the angels and those possessed of knowledge — Maintainer of justice; there is no God but He, the Mighty, the Wise.

اَللّٰہُ لَاۤ اِلٰہَ اِلَّا ہُوَ الۡحَیُّ الۡقَیُّوۡمُ سورة آل عِمرَان3:3 Allah is He beside Whom there is no God, the Living, the Self-Subsisting and All-Sustaining.

اَللّٰہُ لَاۤ اِلٰہَ اِلَّا ہُوَ رَبُّ الۡعَرۡشِ الۡعَظِیۡمِ ۩ سورة النَّمل27:27 Allah! there is no God but He, the Lord of the Mighty Throne.’

قُلۡ اِنَّمَاۤ اَنَا۠ مُنۡذِرٌ ۖ وَّمَا مِنۡ اِلٰہٍ اِلَّا اللّٰہُ الۡوٰحِدُ الۡقَہَّارُ سورة صٓ38:66 Say, I am only a Warner; and there is no God but Allah, the One, the Most Supreme;

ذٰلِکُمُ اللّٰہُ رَبُّکُمۡ خٰلِقُ کُلِّ شَیۡءٍ لَّاۤ اِلٰہَ اِلَّا ہُوَ ۖ فَاَنّٰی تُؤۡفَکُوۡنَ سورة المؤمن40:63 Such is Allah, your Lord, the Creator of all things. There is no God but He. How then are you turned away?

رَّبُّ الۡمَشۡرِقِ وَالۡمَغۡرِبِ لَاۤ اِلٰہَ اِلَّا ہُوَ فَاتَّخِذۡہُ وَکِیۡلًا سورة المُزمّل73:10 He is the Lord of the East and the West; there is no God but He; so take Him as thy Guardian.

غَافِرِ الذَّنۡۢبِ وَقَابِلِ التَّوۡبِ شَدِیۡدِ الۡعِقَابِ ذِی الطَّوۡلِ ۖ لَاۤ اِلٰہَ اِلَّا ہُوَ ۖ اِلَیۡہِ الۡمَصِیۡرُ سورة المؤمن40:4 The Forgiver of sin and the Acceptor of repentance, Severe in punishment, the Possessor of bounty. There is no God but He. Towards Him is the final return.

ہُوَ اللّٰہُ الَّذِیۡ لَاۤ اِلٰہَ اِلَّا ہُوَ ۖ عٰلِمُ الۡغَیۡبِ وَالشَّہٰدَۃِ ۖ ہُوَ الرَّحۡمٰنُ الرَّحِیۡمُ سورة الحَشر59:23 He is Allah, and there is no God beside Him, the Knower of the unseen and the seen. He is the Gracious, the Merciful.

اَللّٰہُ لَاۤ اِلٰہَ اِلَّا ہُوَ ۚ وَعَلَی اللّٰہِ فَلۡیَتَوَکَّلِ الۡمُؤۡمِنُوۡنَ سورة التّغَابُن64:14 Allah! there is no God but He; so in Allah let the believers put their trust.

لَاۤ اِلٰہَ اِلَّا ہُوَ یُحۡیٖ وَیُمِیۡتُ ۖ رَبُّکُمۡ وَرَبُّ اٰبَآئِکُمُ الۡاَوَّلِیۡنَ سورة الدّخان44:9 There is no God but He. He gives life and He causes death. He is your Lord, and the Lord of your forefathers.

لَّقَدۡ کَفَرَ الَّذِیۡنَ قَالُوۡۤا اِنَّ اللّٰہَ ثَالِثُ ثَلٰثَۃٍ ۘ وَمَا مِنۡ اِلٰہٍ اِلَّاۤ اِلٰہٌ وّٰحِدٌ ۚ وَاِنۡ لَّمۡ یَنۡتَہُوۡا عَمَّا یَقُوۡلُوۡنَ لَیَمَسَّنَّ الَّذِیۡنَ کَفَرُوۡا مِنۡہُمۡ عَذَابٌ اَلِیۡمٌ سورة المَائدة5:74 They are surely disbelievers who say, Allah is the third of three;’ there is no God but the One God. And if they do not desist from what they say, a grievous punishment shall surely befall those of them that disbelieve.

فَاِلَّمۡ یَسۡتَجِیۡبُوۡا لَکُمۡ فَاعۡلَمُوۡۤا اَنَّمَاۤ اُنۡزِلَ بِعِلۡمِ اللّٰہِ وَاَنۡ لَّاۤ اِلٰہَ اِلَّا ہُوَ ۖ فَہَلۡ اَنۡتُمۡ مُّسۡلِمُوۡنَ سورة هُود11:15 And if they do not respond to you, then know that it has been revealed replete with Allah’s knowledge and that there is no God but He. Will you then submit?

اِنَّنِیۡۤ اَنَا اللّٰہُ لَاۤ اِلٰہَ اِلَّاۤ اَنَا۠ فَاعۡبُدۡنِیۡ وَاَقِمِ الصَّلٰوۃَ لِذِکۡرِیۡۤ سورة طٰه20:15 Verily, I am Allah; there is no God beside Me. So serve Me, and observe Prayer for My remembrance.

قُلۡ اِنَّمَا یُوۡحٰۤی اِلَیَّ اَنَّمَاۤ اِلٰہُکُمۡ اِلٰہٌ وّٰحِدٌ ۖ فَہَلۡ اَنۡتُمۡ مُّسۡلِمُوۡنَ سورة الاٴنبیَاء21:109 Say, Surely it has been revealed to me that your God is but One God. Will you then submit?’

فَتَعٰلَی اللّٰہُ الۡمَلِکُ الۡحَقُّ ۖ لَاۤ اِلٰہَ اِلَّا ہُوَ رَبُّ الۡعَرۡشِ الۡکَرِیۡمِ سورة المؤمنون23:117 Exalted then be Allah, the True King. There is no God but He, the Lord of the Glorious Throne.

اِنَّمَاۤ اِلٰہُکُمُ اللّٰہُ الَّذِیۡ لَاۤ اِلٰہَ اِلَّا ہُوَ ۚ وَسِعَ کُلَّ شَیۡءٍ عِلۡمًا سورة طٰه20:99 Your God is only Allah, beside Whom there is no God. He embraces all things in his knowledge.

اِلٰہُکُمۡ اِلٰہٌ وّٰحِدٌ ۚ فَالَّذِیۡنَ لَا یُؤۡمِنُوۡنَ بِالۡاٰخِرَۃِ قُلُوۡبُہُمۡ مُّنۡکِرَۃٌ وَّہُمۡ مُّسۡتَکۡبِرُوۡنَ سورة النّحل16:23 Your God is One God. And as to those who believe not in the Hereafter, their hearts are strangers to truth, and they are full of pride.

وَمَاۤ اَرۡسَلۡنَا مِنۡ قَبۡلِکَ مِنۡ رَّسُوۡلٍ اِلَّا نُوۡحِیۡۤ اِلَیۡہِ اَنَّہٗ لَاۤ اِلٰہَ اِلَّاۤ اَنَا۠ فَاعۡبُدُوۡنِ سورة الاٴنبیَاء21:26 And We sent no Messenger before thee but We revealed to him, saying, There is no God but I; so worship Me alone.’

ہٰذَا بَلٰغٌ لِّلنَّاسِ وَلِیُنۡذَرُوۡا بِہٖ وَلِیَعۡلَمُوۡۤا اَنَّمَا ہُوَ اِلٰہٌ وّٰحِدٌ وَّلِیَذَّکَّرَ اُولُوا الۡاَلۡبٰبِ سورة إبراهیم14:53 This is a sufficient admonition for mankind that they may benefit by it, and that they may be warned thereby, and that they may know that He is the only One God, and that those possessed of understanding may ponder.

وَقَالَ فِرۡعَوۡنُ یٰۤاَیُّہَا الۡمَلَاُ مَا عَلِمۡتُ لَکُمۡ مِّنۡ اِلٰہٍ غَیۡرِیۡ فَاَوۡقِدۡ لِیۡ یٰہٰمٰنُ عَلَی الطِّیۡنِ فَاجۡعَل لِّیۡ صَرۡحًا لَّعَلِّیۡۤ اَطَّلِعُ اِلٰۤی اِلٰہِ مُوۡسٰی وَاِنِّیۡ لَاَظُنُّہٗ مِنَ الۡکٰذِبِیۡنَ سورة القَصَص28:39 And Pharaoh said, O chiefs, I know of no God for you other than myself; so burn me bricks of clay, O Haman, and build me a tower, that I may have a look at the God of Moses, though I believe him to be one of the liars.’

وَلَقَدۡ اَرۡسَلۡنَا نُوۡحًا اِلٰی قَوۡمِہٖ فَقَالَ یٰقَوۡمِ اعۡبُدُوا اللّٰہَ مَا لَکُمۡ مِّنۡ اِلٰہٍ غَیۡرُہٗۤ ۖ اَفَلَا تَتَّقُوۡنَ سورة المؤمنون23:24 And We did send Noah to his people, and he said, O my people, serve Allah. You have no God other than Him. Will you not then be righteous?’

قُلۡ اِنَّمَاۤ اَنَا۠ بَشَرٌ مِّثۡلُکُمۡ یُوۡحٰۤی اِلَیَّ اَنَّمَاۤ اِلٰہُکُمۡ اِلٰہٌ وّٰحِدٌ فَاسۡتَقِیۡمُوۡۤا اِلَیۡہِ وَاسۡتَغۡفِرُوۡہُ ۗ وَوَیۡلٌ لِّلۡمُشۡرِکِیۡنَ سورة حٰمٓ السجدہ41:7 Say, I am only a man like you. It is revealed to me that your God is One God; so go ye straight to Him without deviating, and ask forgiveness of Him.’ And woe to the idolaters,

۞ وَقَالَ اللّٰہُ لَا تَتَّخِذُوۡۤا اِلٰہَیۡنِ اثۡنَیۡنِ ۖ اِنَّمَا ہُوَ اِلٰہٌ وّٰحِدٌ ۖ فَاِیّٰیَ فَارۡہَبُوۡنِ سورة النّحل16:52 Allah has said, Take not for worship two gods. There is only One God. So fear Me alone.’

۞ وَمَنۡ یَّقُلۡ مِنۡہُمۡ اِنِّیۡۤ اِلٰہٌ مِّنۡ دُوۡنِہٖ فَذٰلِکَ نَجۡزِیۡہِ جَہَنَّمَ ۚ کَذٰلِکَ نَجۡزِی الظّٰلِمِیۡنَ سورة الاٴنبیَاء21:30 And whosoever of them should say, I am a God beside Him,’ him shall We requite with Hell. Thus do We requite the wrongdoers.

اِتَّبِعۡ مَاۤ اُوۡحِیَ اِلَیۡکَ مِنۡ رَّبِّکَ ۖ لَاۤ اِلٰہَ اِلَّا ہُوَ ۖ وَاَعۡرِضۡ عَنِ الۡمُشۡرِکِیۡنَ سورة الاٴنعَام6:107 Follow that which has been revealed to thee from thy Lord; there is no God but He; and turn aside from the idolaters.

ہُوَ الَّذِیۡ یُصَوِّرُکُمۡ فِی الۡاَرۡحَامِ کَیۡفَ یَشَآءُ ۚ لَاۤ اِلٰہَ اِلَّا ہُوَ الۡعَزِیۡزُ الۡحَکِیۡمُ سورة آل عِمرَان3:7 He it is Who fashions you in the wombs as He wills; there is no God but He, the Mighty, the Wise.  

فَاعۡلَمۡ اَنَّہٗ لَاۤ اِلٰہَ اِلَّا اللّٰہُ وَاسۡتَغۡفِرۡ لِذَنۡۢبِکَ وَلِلۡمُؤۡمِنِیۡنَ وَالۡمُؤۡمِنٰتِ ۗ وَاللّٰہُ یَعۡلَمُ مُتَقَلَّبَکُمۡ وَمَثۡوٰٮکُمۡ سورة محَمَّد47:20 Know, therefore, that there is no God other than Allah, and ask forgiveness for thy frailties, and for believing men and believing women. And Allah knows the place where you move about and the place where you stay.
