Sura Āl-ʿImrān 3:103

وَٱعْتَصِمُوا۟ بِحَبْلِ ٱللَّـهِ جَمِيعًا وَلَا تَفَرَّقُوا۟ وَٱذْكُرُوا۟ نِعْمَتَ ٱللَّـهِ عَلَيْكُمْ إِذْ كُنتُمْ أَعْدَآءً فَأَلَّفَ بَيْنَ قُلُوبِكُمْ فَأَصْبَحْتُم بِنِعْمَتِهِۦٓ إِخْوَٰنًا وَكُنتُمْ عَلَىٰ شَفَا حُفْرَةٍ مِّنَ ٱلنَّارِ فَأَنقَذَكُم مِّنْهَا كَذَٰلِكَ يُبَيِّنُ ٱللَّـهُ لَكُمْ ءَايَٰتِهِۦ لَعَلَّكُمْ تَهْتَدُونَ

wa-iʿtaṣimū biḥabli allāhi jamīʿan wa-lā tafarraqū wa-idhkurū niʿmata allāhi ʿalaykum idh kuntum aʿdaʾan fa-allafa bayna qulūbikum fa-aṣbaḥtum biniʿmatihi ikhwānan wa-kuntum ʿalā shafā ḥufratin mina l-nāri fa-anqadhakum minhā ka-dhālika yubayyinu allāhu la-kum āyātihi la-ʿallakum tahtadūna

And hold fast, all together, by the rope which Allah (stretches out for you), and be not divided among yourselves; and remember with gratitude Allah's favour on you; for ye were enemies and He joined your hearts in love, so that by His Grace, ye became brethren; and ye were on the brink of the pit of Fire, and He saved you from it. Thus doth Allah make His Signs clear to you: That ye may be guided.

Sura al-Anfāl 8:63

وَأَلَّفَ بَيْنَ قُلُوبِهِمْ لَوْ أَنفَقْتَ مَا فِى ٱلْأَرْضِ جَمِيعًا مَّآ أَلَّفْتَ بَيْنَ قُلُوبِهِمْ وَلَٰكِنَّ ٱللَّـهَ أَلَّفَ بَيْنَهُمْ إِنَّهُۥ عَزِيزٌ حَكِيمٌ

wa-allafa bayna qulūbihim law anfaqta mā fī l-arḍi jamīʿan mā allafta bayna qulūbihim wa-lākinna allāha allafa baynahum innahu ʿazīzun ḥakīmun

And (moreover) He hath put affection between their hearts: not if thou hadst spent all that is in the earth, couldst thou have produced that affection, but Allah hath done it: for He is Exalted in might, Wise.

Sura al-Nūr 24:43

أَلَمْ تَرَ أَنَّ ٱللَّـهَ يُزْجِى سَحَابًا ثُمَّ يُؤَلِّفُ بَيْنَهُۥ ثُمَّ يَجْعَلُهُۥ رُكَامًا فَتَرَى ٱلْوَدْقَ يَخْرُجُ مِنْ خِلَٰلِهِۦ وَيُنَزِّلُ مِنَ ٱلسَّمَآءِ مِن جِبَالٍ فِيهَا مِنۢ بَرَدٍ فَيُصِيبُ بِهِۦ مَن يَشَآءُ وَيَصْرِفُهُۥ عَن مَّن يَشَآءُ يَكَادُ سَنَا بَرْقِهِۦ يَذْهَبُ بِٱلْأَبْصَٰرِ

a-lam tara annā allāha yuzjī saḥāban thumma yuʾallifu baynahu thumma yajʿaluhu rukāman fatarā l-wadqa yakhruju min khilālihi wa-yunazzilu mina l-samāʾi min jibālin fīhā min baradin fa-yuṣību bihi man yashāʾu wa-yaṣrifuhu ʿan man yashāʾu yakādu sanā barqihi yadhhabu bil-abṣāri

Seest thou not that Allah makes the clouds move gently, then joins them together, then makes them into a heap? - then wilt thou see rain issue forth from their midst. And He sends down from the sky mountain masses (of clouds) wherein is hail: He strikes therewith whom He pleases and He turns it away from whom He pleases, the vivid flash of His lightning well-nigh blinds the sight.
