Q: What is the lightest sehri a person can have? We have having a debate. Some of us said it must be food. Some said it must be at least a date and water. (Text)
A: So long as something (food/water) goes down your throat with the intent of sehri at the time of sehri, you would gain the reward of the sehri sunnah. Glass of water alone would also suffice. It is a blessed time. Acting upon the practice of sehri would give you a great reward.
Allah Certainly Knows Best.
p.s. Why do you debate in Ramadhaan?
