It was narrated that Aishah said: "The Prophet was shrouded in three white Suhuli garments."
أَخْبَرَنَا قُتَيْبَةُ، عَنْ مَالِكٍ، عَنْ هِشَامِ بْنِ عُرْوَةَ، عَنْ أَبِيهِ، عَنْ عَائِشَةَ، أَنَّ رَسُولَ اللَّهِ صلى الله عليه وسلم كُفِّنَ فِي ثَلاَثَةِ أَثْوَابٍ بِيضٍ سُحُولِيَّةٍ لَيْسَ فِيهَا قَمِيصٌ وَلاَ عِمَامَةٌ .
