وَأَلَّفَ بَيْنَ قُلُوبِهِمْ لَوْ أَنفَقْتَ مَا فِي الأَرْضِ جَمِيعاً مَّا أَلَّفَتْ بَيْنَ قُلُوبِهِمْ وَلَـكِنَّ اللّهَ أَلَّفَ بَيْنَهُمْ إِنَّهُ عَزِيزٌ حَكِيمٌ
[8:63]
And united their hearts; had you spent all that is in the earth, you could not have united their hearts, but Allah united them; surely He is Mighty, Wise.
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.
And (as for the believers) hath attuned their hearts. If thou hadst spent all that is in the earth thou couldst not have attuned their hearts, but Allah hath attuned them. Lo! He is Mighty, Wise.
