Musannaf Ibn Abi Shaybah 31506 — Reports from Abdullah bin Mas'ud

Abu Ubaydah said that when Sayyiduna Abdullah bin Mas'ud (may Allah be pleased with him) strove hard in supplication, he would say: "O Allah, I ask You, by the blessing of Your favour which You have shown me, by the blessing of the good trial with which You have tried me, and by the blessing of Your favours which You have bestowed upon me, that You admit me to Paradise. O Allah, admit me to Paradise through Your mercy, Your forgiveness and Your favour."
