Sunan an-Nasa'i, 2428

It was narrated from Musa bin Talhah that:a man brought a rabbit to the Prophet, and the prophet stretched out his hand toward it, then the one who had brought it said: "I saw some blood on it," So the Prophet drew his hand back, but he told the people to eat. Among the people there was a man who held back. The Prophet said: "What is the matter with you?" He said: "I am fasting." The Prophet said to him: "Why don't you fast on the three days of Al-Bid, the thirteenth, fourteenth and fifteenth?

Rapporté par Moussa ibn Talhah : Un homme apporta un lapin au Prophète, et le Prophète tendit la main vers lui. Mais celui qui l’avait apporté dit : "J’ai vu du sang dessus." Alors le Prophète retira sa main, mais il dit aux gens de manger. Parmi eux, un homme hésita. Le Prophète lui demanda : "Qu’as-tu ?" Il répondit : "Je jeûne." Le Prophète lui dit : "Pourquoi ne jeûnes-tu pas les trois jours d’Al-Bid, le treizième, le quatorzième et le quinzième ?
