Shayban bin 'Abdur Rahman شيبان بن عبد الرحمن النحوي أبو معاوية · Fasting (Kitab Al-Siyam)

The Prophet (ﷺ) said: Snuff up water freely unless you are fasting.

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.

The Messenger of Allah (ﷺ) used to command us to fast the days of the white (nights): thirteenth, fourteenth and fifteenth of the month. He said: This is like keeping perpetual fast.
