Fasting (Kitab Al-Siyam)

Narrated Thawban:

The Prophet (ﷺ) said: A man who cupped and a man who has himself cupped broke their fast. The narrator Shayban said in his version: AbuQilabah told me that AbuAsma' ar-Rahbi told him that Thawban, the client of the Messenger of Allah (ﷺ), told him that he heard the Prophet (ﷺ) say this.
