Question: A person went to sleep before the suhoor in Ramadhaan whilst having the intention to take the suhoor. But, he slept through ’til the morning. Is his fast correct or not?
Response: His fast is correct because the suhoor is not a condition for the correctness of the fast. Rather it is preferable, for that which the Prophet ﷺ said:
«Take the suhoor for certainly in it is blessing». [The authenticity of this hadeeth has been] agreed upon by al-Bukhaaree and Muslim.
