Answered by Shaykh Faraz Rabbani
Due to the shortening of the daylight hours and the close proximity of prayers, I forgot to pray my Asr until the maghrib adhaan was being called. I immediately realised and performed Asr followed by the Maghrib prayer. Is my Asr prayer valid?
Walaikum assalam wa rahmatullah,
The prayer would be valid, but it is sinful to do this deliberately.
Wassalam,
Faraz Rabbani
