﴿ 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.”

See note to 2:191.
