Al-Harith left his will that Abdullah ibn Yazid should offer his funeral prayer; so he prayed over him. He then put him in the grave from the side of his legs and said: This is a Sunnah (model practice of the Prophet).
Sunan Abi Dawud Book 21, Hadith 123
← Previous Hadith That 'Abd al-Rahman b. 'Awf alighted in the grave of the Prophet (ﷺ). He said: I still seem to see the four of them.

Sunan Abi Dawud Book 21, Hadith 122 Next Hadith → We went out with the Messenger of Allah (ﷺ) to the funeral of a man of the Ansar, but when we reached the grave, the niche in the side had not yet been made, so the Prophet (ﷺ) sat down facing the qiblah, and we sat down along with him.

Sunan Abi Dawud Book 21, Hadith 124
