Isma'il bin Abi Khalid al-Ahmsi إسماعيل بن أبي خالد الأحمسي · Funerals (Kitab Al-Jana'iz)

The Messenger of Allah (ﷺ) was shrouded in three garments made in Najran: two garments and one shirt in which he died. Abu Dawud said: The narrator 'Uthman said: In three garments: two red garments and a shirt in which he died.

The Prophet (ﷺ) said: The niche in the side of the grave is for us and the excavation in the middle is for others.
