Syedna Abu Hurairah, may Allah be pleased with him, narrates that a Bedouin brought a roasted rabbit to the service of the Messenger of Allah, peace and blessings be upon him, along with a sauce of mustard and raisins and some curry. He placed it before the Prophet, but the Messenger of Allah, peace and blessings be upon him, did not eat it himself; rather, he instructed his companions to eat. The Bedouin refrained from eating. The Messenger of Allah, peace and blessings be upon him, asked him: Why are you not eating? He replied: I fast three days every month (and today I am fasting). The Prophet, peace and blessings be upon him, said: If you wish to fast, then fast on the white days.
