Does Sehri Substitute the intention for Fasting?

Q: Saum-25: Will the fast be valid if one forgot to say the intention at the time of Sehri?

Answer: Even if one did not state the intention of fasting at the time of Sehri eating the Sehri is in itself the intention for fasting.

N.B. During Ramadhaan. it is permissible to make the intention for fasting anytime before midday (the time exactly between sunrise and sunset) as long as one did not eat before that. And Allaah knows best what is most correct.
