Speech of opposition : It is legal to say kunute nazila dua in Fazar prayer during the time of trouble. becaush Huzur Pak Sallallahu Alaihi Wasallam did that for one month.
What is said in Islam : Although Huzur Pak Sallallahu Alaihi Wasallam said kunute nazila dua in Fazar prayer for one month, in the next time this was ‘Mansukh (stopped). so before and after that time this deed was never performed. Even Hazrat Sahabaee Kiram Radiallahu Anhu never did that. So except Hazrat Imam Shafi Rahmatullahi Alaihi, other followers of Imaam Abu Hanifa, Imam Abu Yusuf and Imam Muhammad Rahmatullahi Alaihi should not say kunute nazila even in the time of war. If some one of Hanafi Mazhab follow that, then his Namaaz should be repeated.
