The fasting person who performs ablution and water enters his throat

Sayyiduna Ibn Abbas (may Allah be pleased with them both) and al-Sha'bi say: If he was performing ablution for some purpose other than prayer, he will make up that fast. If he was performing ablution for prayer, no make-up is required of him.

And the same is narrated from al-Sha'bi; they both said: If it was for something other than prayer, he makes up the fast; and if it was for prayer, there is no make-up upon him.

Al-Hasan used to say: If someone rinsed his mouth while fasting and water went down his throat unintentionally, nothing is required of him. He will complete his fast.

Hammad says: If, while rinsing the mouth, water goes down the throat of a fasting person, then if the ablution was obligatory nothing is required of him. If he was rinsing for some other reason, he will repeat the fast.

Ibn Jurayj says: A man said to Ata: I was cleaning my nose and water went down my throat; is there any harm in that? He said: No, there is no harm in it; you had no control over it.

Ibrahim says concerning a fasting person down whose throat the water of ablution goes: If he was mindful of his fast, he will make it up; and if he had forgotten his fast, nothing is required of him.

Amr bin Harim says: Jabir bin Zayd was asked: If a man is fasting and while performing ablution water goes down his throat, will his fast be broken? He said: No, he should complete his fast.
