I entered the mosque and the
adhaan was being given for the prayer. Should I pray Tahiyyat al-Masjid or wait until the
adhaan finishes?
It is better to respond to the adhaan first, then pray Tahiyyat al-Masjid, so as to combine two virtuous deeds. But the issue is flexible.
And Allaah is the source of strength. May Allaah bless our Prophet Muhammad and his family and companions.
