It is narrated from Hazrat Abu Hurairah that the Messenger of Allah, peace and blessings be upon him, said three times: "Refrain from continuous fasting (Saum Wisal)." The people said, "But you also observe continuous fasting?" He replied, "I am not like you. I spend the night in such a state that my Lord feeds me and gives me drink. Undertake only those deeds for which you have the strength."

Hazrat Aisha (may Allah be pleased with her) says that the meaning of the verse of the Holy Qur'an { ثُمَّ أَتِمُّوا الصِّیَامَ إلَی اللَّیْلِ } is that continuous fasting (without breaking the fast) is disliked.

Hazrat Abu Al-Aaliyah, regarding continuous fasting (Saum Wisal), says that Allah, the Lord of Majesty, has stated { ثُمَّ أَتِمُّوا الصِّیَامَ إلَی اللَّیْلِ } Thus, in the light of this verse, when night comes, his fast is completed; now if he wishes, he may fast again, and if he wishes, he may not.

Hazrat Aamir says that Hazrat Ibn Abi Nu'm kept the fast of wisal for fifteen days. Then we stopped him from it.

Hazrat Abu Nofal bin Abi Aqrab narrates that I came to Hazrat Ibn Zubair on the fifteenth day of the month; he was observing continuous fasting (Sawm Wisal).

Hazrat Sa’d bin Abi Waqqas narrates that once the Holy Prophet (peace and blessings be upon him) struck one of his hands on the other and said,“A month is like this, a month is like this.”Then, the third time, he kept one finger less.

Hazrat Umar narrates that the Noble Prophet (peace and blessings be upon him) stayed away from his wives for a month. When twenty-nine days had passed, Hazrat Jibreel came and said, "The month has passed and you have fulfilled your oath."

Hazrat Abu Huraira narrates that once the Messenger of Allah, peace and blessings be upon him, said: "How many days of the month have passed?" We said, "Twenty-two days have passed and eight remain." The Noble Prophet, peace and blessings be upon him, said: "No, rather twenty-two days have passed and seven days remain. Seek it in the night." Then the Noble Prophet, peace and blessings be upon him, said: "A month is like this, a month is like this." He said this three times and paused once.

Hazrat Jabir narrates that once the Holy Prophet (peace and blessings be upon him) took an oath not to go to his wives for a month and went to an upper room. When twenty-nine days had passed, Hazrat Jibreel appeared and said, "A month has passed, please come down."

It is narrated from Hazrat Ibn Umar (may Allah be pleased with them both) that the Messenger of Allah (peace and blessings be upon him) said: We are an unlettered nation; we neither write nor calculate. The month is like this, like this, and like this. On the third time, he folded his thumb (i.e., counted up to twenty-nine). Then he said: The month is like this, like this, and like this. This time, he counted up to thirty.
