Abdul Warith bin Sa'id bin Dhakwan عبد الوارث بن سعيد بن ذكوان · Fasting (Kitab Al-Siyam)

The Prophet (ﷺ) as saying: A man who cups and a man who gets himself cupped break their fast. Abu Dawud said: Ibn Thawban transmitted a similar tradition from his father on the authority of Makhul through an chain of narrators mentioned by him.

The Prophet (ﷺ) said: if one has a sudden attack of vomiting while one is fasting, no atonement is required of him, but if he vomits intentionally he must make atonement.

The Messenger of Allah (ﷺ) said: If anyone has a riding beast which carries him to where he can get sufficient food, he should keep the fast of Ramadan wherever he is when it comes.

Hunaydah al-Khuza'i reported on the authority of her mother who said: I entered upon Umm Salamah and asked her about fasting. She said: The Messenger of Allah (ﷺ) used to command me to fast three days every month beginning with Monday or Thursday.
