Sayyidi wa sanadi Mawlana Mohammad Taqi Usmani (Allah preserve him and allow us to benefit from him abundantly, Ameen) said:

“When in trouble or in a perplexing situation immediately repent (make tauba) before asking Allah for help & assistance.

There are definitely many sins we are not even aware of committing. Moreover, our worship itself is full of faults. Repenting from all these is a must.

An aftermath of sin (ma’seyat) is that it causes your decision making abilities to become cloudy/muddy. You forget things and make wrong judgements. Repentance will remove these and making your thinking and decision making clearer.”
