I did it for 3 days. In mid of asar and maghrib. 41 times and u must have 2 or 3 mire ppl with u to read. I did it on 9th 10th and 11th of muharram had roza as well. After asar prayers i use to sit with my mom czn and her grand mother and we use to recite it 41 times and awal o akhir 11 times durood sharif.Just frequently reciting it? ya koi khas wakat pe ya nafal kai baad?
