Takhrij Hadith 1186: "Indeed, Rajab is a tremendous…"

Indeed, Rajab is a tremendous month in which good deeds are multiplied. So whoever fasts a day from Rajab, it is like fasting a year; and whoever fasts seven days, seven gates of Hellfire are closed from him; and whoever fasts eight days, eight gates of Paradise are opened for him; and whoever fasts ten days, he does not ask Allah the Mighty and Majesticfor anything except that He gives it to him; and whoever fasts fifteen days, a caller calls out from the heaven: Indeed, what has passed has been forgiven for you, so resume your deeds, and your bad deeds have been replaced with good deeds.
