Assalamu Alaikum Wa rahmatullahi Wa barakatuhu.

My dear brothers and sisters in islam without much wordings, you and I knows that we a in a society where in one way or the other we usually wrong ourself by SINNING. may Allah forgive us. looking at how serious the act of repentance and seeking Allah's forgiveness is, one of the islamic Scholars Sheik Salih Muhammad extracted a book from some writing work of the Scholars before him in other to make learning and understanding the act of repenting and seeking Allah's forgiveness easier for brothers and sisters in Islam.

The idea of designing this application came to me when i realized how important it is to our society and student of knowledge, May Allah Forgive Us, Ameen
