Asalaamu Alaykum, so I wanted to ask if I’m praying Salah at home and I’m following a timetable and say the beginning time of Asr starts at 2:00pm and the adhan in the mosque is at 2:20, should I wait for the adhan to begin praying or can I start praying at the start time for the prayer which is at 2:00pm?
Also, if I live in a western country where the adhan isn’t recited aloud in most mosques and I’m praying at home or at work on my own, do I have to recite the adhan and iqamah or is the iqamah itself sufficient?
