Assalam o' Alaikum, I have a question regarding making the intention of fast while not being completely in one's senses. This morning I was half-asleep and thought that I had missed the fast of Shab-e-Barat, so while I was still not completely out of my sleep, I made the intention of the fast. But when I fully woke up, I realized that the day of Shab-e-Barat was yesterday and I had no intention of keeping a fast for today. My question is do I have to keep a fast now or does my intention of fast not count since I was not in a completely clear state of mind? JAZAKALLAH.
For a voluntary Fast, one is allowed to make intention even until mid day but for an obligatory Fast, intention must be made at night before the the time of Suhoor ends.
Since you did not make your intention of a voluntary Fast in full conciousness, therefore it is not obligatory upon to continue with the Fast.
And Allah knows best.
