Narrated Abu Sa`id: That he had heard the Prophet saying, Do not fast continuously (practice Al-Wisal), and if you intend to lengthen your fast, then carry it on only till the Suhur (before the following dawn). The people said to him, But you practice (Al-Wisal), O Allah's Apostle! He replied, I am not similar to you, for during my sleep I have One Who makes me eat and drink.
