I could not find this Hadith in Sahih Muslim compilation. It is suppose to be in the Book of Prayers (Kitab-as-Salaat).
I am not sure who this man is to give an extremely poor “fatwa”. I am not going to spend time and effort here to destroy this fatwa with Quran which is really easy even for the likes of us here…
Most shuyukh like the renowned Qaradawii and Hamza have not issued anything like that.
