Sahih al-Bukhari, Book 23, Hadith 35 (In-Book)

Narrated Aisha: Allah's Messenger was shrouded in three pieces of cloth which were made of white Suhul and neither a shirt nor a turban were used.

حَدَّثَنَا إِسْمَاعِيلُ، قَالَ حَدَّثَنِي مَالِكٌ، عَنْ هِشَامِ بْنِ عُرْوَةَ، عَنْ أَبِيهِ، عَنْ عَائِشَةَ ـ رضى الله عنها ـ أَنَّ رَسُولَ اللَّهِ صلى الله عليه وسلم كُفِّنَ فِي ثَلاَثَةِ أَثْوَابٍ بِيضٍ سَحُولِيَّةٍ، لَيْسَ فِيهَا قَمِيصٌ وَلاَ عِمَامَةٌ‏.‏
