Sayyiduna Abdullah bin Mas'ud (may Allah be pleased with him) said: The Messenger of Allah (peace and blessings be upon him) taught me: "All reverences, prayers and pure words are for Allah alone. O Prophet, peace be upon you, and the mercy of Allah and His blessings. Peace be upon us and upon the righteous servants of Allah. I bear witness that there is no deity except Allah, and I bear witness that Muhammad (peace and blessings be upon him) is His servant and His Messenger. O Allah, send Your mercy upon Muhammad (peace and blessings be upon him) and the people of his household, as You sent mercy upon Ibrahim; indeed, You are Praiseworthy, Glorious. O Allah, send Your mercy upon us along with them. O Allah, send Your blessings upon Muhammad (peace and blessings be upon him) and the people of his household, as You sent blessings upon Ibrahim; indeed, You are Praiseworthy, Glorious. O Allah, send Your blessings upon us along with them. May the mercies of Allah and the supplications of the believers be upon Muhammad (peace and blessings be upon him), the unlettered Prophet; peace be upon him, and the mercy of Allah and His blessings."
