Questioner:

‘What is the ruling on the ʾathān of Fajr being called [in Ramaḍān] whilst he is having intercourse with his wife?’

Shaykh Muḥammed ibn Hādī al-Madkhalī:

Meaning the caller to prayer has called the ʾathān and he is having intercourse with his wife. It is obligatory upon him to stop and there is nothing upon him.
