sir Assalamu Alikum. I am student of Engineering. Sometimes it happens that i lose my concentration on my work, study though it is time to do work but then i usually go to internet and wast my time. in this situation can i offer Nafal Salah and in Sizdha, can i pray to Allah (swt) to prevent me from Saetan and guide me to concentrate in my work? jazāk Allāhu khayran.from Dhaka.
