Musnad Abu Ya'la al-Mawsili 150:324

Muhammad ibn 'Abbad narrated to us, 'Abd al-'Aziz ibn Muhammad narrated to us, from Hisham ibn 'Urwah, from his father, from 'Aishah, that the Prophet (may Allah bless him and grant him peace) was shrouded in three Sahuli garments, and a lahd (niche) was made for him, and bricks were set up over him.
