Something placed in the niche grave beneath the deceased

Al-Hasan said that a red velvet cloth was placed in the blessed grave of the Prophet (peace and blessings be upon him), which had come to him among the spoils of the Battle of Khaybar, because the land of Madinah was salty and marshy.

Sayyiduna Ibn Abbas (may Allah be pleased with them both) said that a red velvet cloth was placed in the blessed grave of the Prophet (peace and blessings be upon him).

Ja'far narrates from his father, who said: A lahd (niche grave) was made for the Messenger of Allah (peace and blessings be upon him), and Sayyiduna Shuqran (may Allah be pleased with him) placed in his grave a velvet cloth on which he (peace and blessings be upon him) used to ride during his lifetime.
