If somebody offered salah in the impurity state, knowingly did he commit kufr? What is the level of this sin and how to repent this? Please answer.

(Fatwa: 794/794/M=06/1435)

If someone offered salah in the state of impurity unknowingly then he shall not be termed kafir. But it is severe sin to do so and there is fear of kufr if it is done intentionally. It is necessary to do taubah and istighfar. And in each case he should reoffer the salah.

Allah knows Best!
