Did it reach us from the Prophet (peace and blessings be upon him) that he used to continue fasting? And is it a recommended practice for one who is able to continue fasting, or is it specific to him?

The Shaykh : Here is a question that says: It is established that the Messenger of Allah (peace and blessings be upon him) used to continue fasting. Is this a recommended practice for anyone in his Ummah (the Muslim community) who is able to continue fasting, or is it a ruling specific to the Messenger of Allah (peace and blessings be upon him)? And what is the evidence for that? The Shaykh: Continuing in fasting is a ruling specific to the Messenger (peace and blessings be upon him), so it is not permissible for a Muslim to continue fasting from the day into the night. This is because the Prophet (peace and blessings be upon him) explicitly expressed disapproval of the Companions who imitated him in continuing to fast. It is reported in the authentic collections: "The Prophet (peace and blessings be upon him) continued fasting one day," meaning he fasted the day and the night without breaking his fast. "Some of his Companions continued with him, then the Messenger (peace be upon him) continued the second day, and so on for the third day. Some of the Companions were persistent in continuing to fast, so the Messenger (peace be upon him) forbade them and said to them: Beware of continuing to fast. They said: O Messenger of Allah, you do continue to fast! He said: إنِّي لست مثلكم I am not like you Or he said: لست كأحدكم ، إني أبيتُ عند ربي يُطعِمُني ويَسقيني I am not like any of you; I stay by my Lord, who feeds me and gives me drink. This is explicit text that continuing in fasting is a ruling specific to the Messenger (peace and blessings be upon him), so it is not permissible for anyone else to continue after he forbade his Ummah (the Muslim community) with a general prohibition against it.
