Abu Huraira reported God’s Messenger as saying, “No one will express a greeting to me without God restoring my spirit to me so that I may respond to his greeting.”
It is transmitted by Abu Dawud and by Baihaqi in ad-da'awat al-kabir.
He reported that he had heard God’s Messenger say, “Do not turn your houses into graves,* and do not make my grave a place to gather as for visitation, but invoke blessings on me, for your blessing will reach me wherever you are.”
*This is most probably a figurative expressive indicating that a house in which prayer is not offered is like a grave, as God is not worshipped there.
Ibn Mas'ud reported God’s Messenger as saying, “The one who will be nearest me on the day of resurrection will be the one who invoked most blessings on me.”
