Nafi' narrates from Ibn Umar (may Allah be pleased with them both) that the Prophet (peace and blessings be upon him) forbade continuous fasting (wisal). They said: But you (peace and blessings be upon him) also practise wisal? He (peace and blessings be upon him) said: "I am not like you; indeed, I am given food and drink."
