Fasting (Kitab Al-Siyam)
Dawud :: Book 13 : Hadith 2451
Narrated Aisha, Ummul Mu'minin:
Some food was presented to me and Hafsah. We were fasting, but broke our fast. Then the Apostle of Allah (peace_be_upon_him) entered upon us. We said to him: A gift was presented to us; we coveted it and we broke our fast. The Apostle of Allah (peace_be_upon_him) said: There is no harm to you; keep a fast another day in lieu of it.
