Shahada While Terminally Ill
There is no restriction on repenting unless man experiences the coming of death. Punishment comes with crime. if no crime is committed or, one has repented, he should not assume that God is punishing him for no reason. Diseases or other problems do come to all, regardless of their being Muslim or non-Muslim. Life is a test and we all are heading to meet God, sooner or later.
What do you mean with experiencing the coming of death? I have a deadly disease and I know that dead comes in some months (but not like today or tomorrow) is my shahada and repentance still accepted? (even tho my shahada happened after this deadly disease which I believe is a punishment from God)?
