A Pray Before Praying

Amir al-Muminin (A.S) said: “do not read any prayer unless you say this at its beginning:”

صَلِّ عَلَى مُحَمَّدٍ وَآلِ مُحَمَّدٍ وَافْعَلْ بِي كَذَا وَكَذَا.

Bless Muhammad (P.B.U.H) and his family and do to me such and such (and ask for your wants).

And also, he always did this. He was asked about it and he replied: “the prayer which is accompanied by sending blessings to the Prophet and his family is accepted and God Almighty is embarrassed if a servant asks for two prayers and He wants to answer one of the requests and ignores the other one.
