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

Prayers (Salat)
Chapter: To pray without a Rida
Narrated Muhammad bin Al-Munkadir:
I went to Jabir bin `Abdullah and he was praying wrapped in a garment and his Rida was Lying beside him. When he finished the prayers, I said "O `Abdullah! You pray (in a single garment) while your Rida' is lying beside you." He replied, "Yes, I did it intentionally so that the ignorant ones like you might see me. I saw the Prophet (ﷺ) praying like this. "
