As-salāmu ‘alaykum Shaykh. If someone comes for congregational prayer but must leave immediately after, and the imam is delayed 5–10 minutes, and he is in a hurry, what should he do: pray alone, leave the mosque, or something else? Jazākallāhu khayran

Ustadh AbdulAziz al-Haqqan
If he has an urgent situation, he can pray and leave due to the delay of the imam.
