Musannaf Ibn Abi Shaybah

Whenever Hazrat Mujahid would lower the deceased into the grave, he would say: In the name of Allah and in the way of Allah. O Allah, expand his grave for him, illuminate it for him, join him with his Prophet (peace and blessings of Allah be upon him), and be pleased with him, not angry. With the name of Allah and in the way of Allah, O Allah, make his grave spacious, make his grave bright, unite him with his Prophet (peace be upon him), be pleased with him and do not be displeased.
