If someone misses Maghrib due to a doctor’s appointment and prays it at Isha time, are they sinful? They intended to pray at the clinic but arrived late, so they performed Maghrib at Isha time.

Ustadh AbdulAziz al-Haqqan

Be very careful not to miss the time of the salah, so if there was heedlessness from you then yes it is a sin, if not then you are pardoned as u were not able and u did what u could.
