Narrated Abu Talha told of God’s Messenger coming one day with a cheerful look on his face and saying:
Gabriel came to me and told me that my Lord says, “Does it not please you, Muhammad, that none of your people will invoke a blessing on you without my blessing him ten times, and that none of your people will give you a greeting without my greeting him ten times?”
He reported God’s Messenger as saying, “May he be abased who does not invoke a blessing on me when I am mentioned in his presence. May he be abased who passes through the whole of Ramadan before his sins are forgiven him. May he be abased one or both of whose parents have reached old age without causing him to enter paradise.*
Ubayy b. Ka'b said he told God’s Messenger that he frequently invoked blessings on him and asked how much of his prayer* he should devote to him. He replied that he might devote as much as he wished, and when he suggested a quarter he said, “Whatever you wish, but if you increase it that will be better for you.” He suggested a half and he replied, “Whatever you wish, but if you increase it that will be better for you.” He suggested two-thirds and he replied, “Whatever you wish, but if you increase it that will be better for you.” He then suggested devoting all his prayer to him and he replied, “Then you will be freed from care and your sin will be expiated.”
* The word used is salat. It has been explained as referring here to the petitions (du’a) offered at the end of the salat.
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.
