Musnad Ahmad 32:1517

'Abd al-Wahhab narrated to us, he said: Sa'id was asked about *al-wisal* (continuous fasting without breaking it at night), and he informed us from Qatadah, from Anas, that the Messenger of Allah (peace and blessings of Allah be upon him) said: "Do not practice *wisal*." It was said to him: "You practice *wisal*, O Messenger of Allah." He said: "I am not like any one of you; my Lord feeds me and gives me drink."
