Hadith 6:900
Waki’ narrated to us, from Sufyan, from Layth, from Mujahid, that he used to say: "In the name of Allah and in the way of Allah. O Allah, open for him in his grave, and illuminate it for him therein, and join him with Your Prophet, may Allah bless him and grant him peace, while You are pleased with him, not angry."
حدثنا وكيع عن سفيان عن ليث عن مجاهد أنه كان يقول بسم الله وفي سبيل الله اللهم افتح له في قبره ونور له فيه والحقه نبيه صلى الله عليه وسلم وأنت عنه راض غير غضبان
