101 Dua’a: Dua’a For great sawab and protection from major sins

Ibne Babviya (r.a) has though reliable sources reported that Hazrat Ali (a.s) said that he who recites this Dua’a thrice by evening or any time up to the end of evening he will not miss any good action that night and all evils and mischiefs will remain away from him. And he who recites this Dua’a in the morning will also get the same reward. 

So Glory be to Allah when you enter the evening and when you enter the morning, and for Him (alone) is all the praise in the heavens and the earth, at the sun’s decline and when you enter the noon.
