“Allah’s Messenger [saws] forbade al-wisal in observing As-Saum. So one of the Muslims said to him, ‘But you practice al-wisal O Allah’s Messenger [saws]!’ The Prophet [saws] replied, ‘Who amongst you is similar to me? I am given food and drink during the night by my Lord.’ So when the people refused to stop al-wisal the Prophet [saws] observed saum day and night continuously along with them for a day and then another day and then they saw the crescent-moon [of the month of Shawwal]. The Prophet [saws] said to them, ‘If it [the crescent] had not appeared I would have made you observe saum for a longer period.’ That was as a punishment for them when they refused to stop [practicing al-wisal].”[100]
“The Messenger of Allah [saws] forbade al-wisal. A man among the Muslims said, ‘But you practice wisal O Messenger of Allah [saws].’ The Messenger of Allah [saws] said, ‘Who among you is like me? During the night, my Lord feeds me and gives me to drink.’ When they refused to stop practicing wisal he fasted continuously with them day after day then they saw the crescent. He said, ‘If the crescent had been delayed I would have made you fast more,’ as if he wanted to teach them a lesson when they refused to stop.”[101]
Unless breaking the fast by the following dawn
“Do not saum continuously and if you intend to lengthen your saum then carry it on only till the sahur [before the following dawn]” The people said to him, “But you practice [al-wisal] O Allah’s Messenger [saws]!” He replied, “I am not similar to you for during the night I have One Who makes me eat and drink.”[102]
“Do not fast wisal. If any one of you wants to fast continuously he should only do so until prior to dawn.” They said, “But you practice wisal.” He said, “I am not like you I have One Who provides me with food and provides me with drink.”[103]
“Allah’s Messenger [saws] said, ‘Do not observe saum continuously day and night and if any one of you intends to saum continuously day and night he should continue till the sahur [before the following dawn].’ They said, ‘But you practice al-wisal O Allah’s Messenger [saws]!’ The Prophet [saws] said, ‘I am not similar to you; during the night I have One Who makes me eat and drink.’”[104]
Prohibited to fast every day
“It was said, ‘O Messenger of Allah [saws]! What is the case of the one who fasts daily?’ He said, ‘He did not fast nor break [the fast].’”[105]
“The Messenger of Allah [saws] said, ‘Whoever fasts every day of his life then he has neither fasted nor broken his fast.’”[106]
“The Messenger of Allah [saws] said, ‘The one who fasts every day of his life has neither fasted nor broken the fast.’”[107]
