Assalam u Alaikum!
I have a question some Muslim acholar have said that a guy called him and told him that he saw Prophet MUHAMMAD ( P.B.U.H ) in his dreams and he asks to read 3 times Surah Fatiha , 3 times Surah Alilhlas and 313 times HABUNALLAHU WA NAIMAL WAQEEL.
My question is there is no hadeeth related to 313 times reading HABUNALLAHU WA NAIMAL WAQEEL.
Please advise for the above in the light of islam.
JAZAKALLAH
