Does committing sins at night affect the fast during the day?
Machine translationRead the Arabic original
Question : He says: Honorable Shaykh, the saying of the Prophet Bulugh al-Maram 5:14 Does doing these things at night count the same as doing them during the day? Please give me a ruling; may Allah reward you.
Answer : The meaning is doing these things during the day, because he said, "Allah has no need for one to leave his food and drink." Does one leave food and drink at night, or during the day? During the day. So, if a person commits a sin at night, but during the day, when he is fasting, he restrains himself, then that does not affect his fast. That is, the sins he commits at night do not affect his fast. However, in any case, every person is obligated to avoid sin. If his soul incites him to commit it, he must stop and repent immediately.
The Messenger of Allah (ﷺ) said: “Whoever does not give up forged speech and evil actions and does not abandon foolishness, Allah is not in need of his leaving food and drink
صلى الله عليه وسلم من لم يدع قول الزور والعمل به والجهل فليس لله حاجة في أن يدع طعامه وشرابهAnswer : The meaning is doing these things during the day, because he said, "Allah has no need for one to leave his food and drink."
