n this video clip both #MuftiMenk and Dr. Muhammad Salah say how to send salutations and blessings to the prophet Muhammed sallallahu alaihi wasallam and the two benefits for doing that. They discussed the following hadith.
Ubayy ibn Ka‘b (ra) said: I said: O Messenger of Allah, I send a great deal of blessings upon you; how much of my du‘aa’ should be sending blessings upon you? He said: “Whatever you wish.” I said: One quarter? He said: “Whatever you wish, and if you do more, that will be better.” I said: One half? He said: “Whatever you wish and if you do more, that will be better.” I said: Two thirds? He said: “Whatever you wish and if you do more, that will be better.” I said: I will make all of my du‘aa’ for you. He said: “Then your concerns will be taken care of and your sins will be forgiven.” Narrator: Ubayy ibn Ka‘b; Status of the hadith: hasan; Muhaddith: Ibn Hajar al-‘Asqallaani; Source: Muwaafaqat al-Khabr al-Khabr, p. 340/2, hadith no. 71475
