Machine translationRead the Arabic original
Question:
If a person intended to fast for a day, for example, or for several days, and then slept after the prayer on that day, how does he fast that day? Is it permissible for him to fast during that day if he is fasting during it?
Answer:
If he did not fast, or if he ate or drank after he had fasted, then this is not valid. But if he fasted and then ate or drank after he had intended to fast, having eaten or drunk while forgetting, his fast is completed, as the Prophet (peace and blessings be upon him) said:Sahih al-Bukhari 1933.

for what he has eaten or drunk, has been given to him by Allah.
