AL ANFAAL — Ayat 63

وَأَلَّفَ بَيْنَ قُلُوبِهِمْ لَوْ أَنفَقْتَ مَا فِي الأَرْضِ جَمِيعاً مَّا أَلَّفَتْ بَيْنَ قُلُوبِهِمْ وَلَـكِنَّ اللّهَ أَلَّفَ بَيْنَهُمْ إِنَّهُ عَزِيزٌ حَكِيمٌ

And brought together their hearts. If you had spent all that is in the earth, you could not have brought their hearts together; but Allah brought them together. Indeed, He is Exalted in Might and Wise.
