Sayyiduna Abu Sa'id Khudri (may Allah be pleased with him) narrates a hadith from the Messenger of Allah (peace and blessings be upon him) similar to the hadith of Sayyiduna Ibn Umar (may Allah be pleased with them both) regarding wisal (continuous fasting). He said: "So which one of you has observed wisal from one suhoor to the next suhoor (kept a continuous fast)?"

Imam Abu Bakr (may Allah have mercy on him) says that in the narration of Hazrat Talhah bin Ubaidullah, regarding the question about Islam from the Prophet Muhammad (peace be upon him), it is mentioned that the Prophet (peace be upon him) said: "And the fasting of Ramadan (is obligatory upon you)." He asked, "Are there any other fasts obligatory upon me besides this?" The Prophet (peace be upon him) said: "No, except that you observe voluntary fasts."

Sayyiduna Abu Bakr (may Allah be pleased with him) narrates from the Noble Prophet (peace and blessings be upon him) that he (peace be upon him) said: "None of you should ever say that I have fasted the entire Ramadan or that I have stood (in prayer) the entire Ramadan. And Allah knows best. The Prophet (peace and blessings be upon him) disliked that his Ummah declare themselves pure or righteous, or he said that sleep or heedlessness is inevitable (it does happen)."
