﴿ وَأَلَّفَ بَيْنَ قُلُوبِهِمْ ۚ لَوْ أَنفَقْتَ مَا فِى ٱلْأَرْضِ جَمِيعًۭا مَّآ أَلَّفْتَ بَيْنَ قُلُوبِهِمْ وَلَٰكِنَّ ٱللَّهَ أَلَّفَ بَيْنَهُمْ ۚ إِنَّهُۥ عَزِيزٌ حَكِيمٌۭ ﴾

“whose hearts He has brought together: [for,] if thou hadst expended all that is on earth, thou couldst not have brought their hearts together [by thyself]: but God did bring them together. Verily, He is almighty, wise.”

(And (as for the believers) hath attuned their hearts) he united their hearts and word by means of Islam. (If thou hadst spent all that is in the earth) of gold and silver (thou couldst not have attuned their hearts) or their word, (but Allah hath attuned them) He united their hearts by means of faith. (Lo! He is Mighty) in His kingdom and sovereignty, (Wise) in His command and decree.
