Bismillahi Walaikum assalam But can this be really hung on the wall for I heard leaving the salah in the prescribed time and making qaza is indeed a sin and normally the sins should be hidden and so are the qaza salahs as I heard in a bayan. So i think one has to keep the qaza salahs to himself and his spiritual guide. Allahu alam I may be wrong. I hope someone could correct. Wassalam.
