Q 2: What is the ruling on
someone who intended Sawm (Fast) in the morning after the break of dawn
though they have not drunk or eaten anything?
It is valid to have the intention to observe Sawm on the day if it is a supererogatory Sawm. If Sawm of that day is Wajib (obligatory), it is invalid if there is no intention before dawn. The Prophet (peace be upon him) stated:
Whoever does not determine to fast by night has not fasted.
May Allah grant us success. May peace and blessings be upon our Prophet Muhammad, his family, and Companions.
