Sahih al-Bukhari, Volume 2, Book 23, Hadith 361 (USC-MSA) ⓘ
Narrated `Aisha: The Prophet was shrouded in three pieces of cloth which were made of Suhul (a type of cotton), and neither a shirt nor a turban were used.
حَدَّثَنَا أَبُو نُعَيْمٍ، حَدَّثَنَا سُفْيَانُ، عَنْ هِشَامٍ، عَنْ عُرْوَةَ، عَنْ عَائِشَةَ ـ رضى الله عنها ـ قَالَتْ كُفِّنَ النَّبِيُّ صلى الله عليه وسلم فِي ثَلاَثَةِ أَثْوَابِ سَحُولَ كُرْسُفٍ، لَيْسَ فِيهَا قَمِيصٌ وَلاَ عِمَامَةٌ.
