When does the time for the Fajr prayer begin?
Praise be to Allah, and peace and blessings be upon our Master, the Messenger of Allah.

What is the ruling on someone who fasts but does not pray?
A Muslim must be diligent in fulfilling all obligations, and after the Shahadah, prayer is the most important duty.

● If they abandon prayer out of laziness, they are still a Muslim, and their fasting remains valid, but they have committed a grave sin by neglecting prayer.

Is it a condition for the mosque where I‘tikaf is performed to hold Jumu‘ah prayers?
No, it is not a condition for the mosque where I‘tikaf is performed to have Jumu‘ah prayers. However, if a person vows to perform continuous I‘tikaf, and Jumu‘ah occurs within that period, then they must observe I‘tikaf in a mosque where Jumu‘ah is held so that they do not break their continuity by leaving for Friday prayer.
