Jami` at-Tirmidhi Book 10, Hadith 83
His father said: "The one who made the Lahd in the grave of the Messenger of Allah was Abu Talhah. And the one who placed the velvet cloth under him was Shuqran a freed slave of Messenger of Allah."
"When he Prophet put the deceased in the grave" He said: And Abu Khalid (one of the narrators) said : "When he placed the deceased in the Lahd" - "He said one time: 'In the Name of Allah, by His command and upon the Millah of the Messenger of Allah.' and one time he said: 'In the Name of Allah, by His command and upon the Sunnah of the Messenger of Allah."
"A red velvet cloth was placed in the grave of the Prophet."
