Sayyiduna Abdullah bin Umar (may Allah be pleased with them both) narrates: The people went out to sight the moon. I informed the Noble Prophet (peace and blessings be upon him): I have also seen the moon. So the Noble Prophet (peace and blessings be upon him) himself fasted and ordered the people to fast as well. Marwan bin Muhammad has narrated this report from Ibn Wahb, and he is unique in transmitting it, and this narrator is trustworthy.

This narration is also transmitted with another chain of transmission.

Tawoos narrates: I was present in Madinah Munawwarah, and there were also Sayyiduna Abdullah bin Umar and Sayyiduna Abdullah bin Abbas (may Allah be pleased with them). A person came to the governor there and gave testimony of sighting the moon (i.e., the moon of Ramadan). So the governor asked Sayyiduna Abdullah bin Abbas and Sayyiduna Abdullah bin Umar (may Allah be pleased with them) about the testimony of this person. Both of them said: His testimony should be accepted. Then both of them stated that the Noble Prophet (peace and blessings be upon him) had accepted the testimony of one person regarding the sighting of the Ramadan moon. Both of these gentlemen also stated that the Noble Prophet (peace and blessings be upon him) used to accept the testimony of only two men regarding the moon of Eid al-Fitr. In narrating this report, the narrator named Abu Isma'il Hafs is unique, and he is weak.

Lady Aisha (may Allah be pleased with her) narrates: The Prophet Muhammad (peace be upon him) used to pay as much attention to the crescent of Sha'ban as he did to the crescent of Ramadan. Then he would fast upon sighting the crescent. If it was cloudy, he would complete the count of thirty days and then begin fasting. The chain of this hadith is Hasan Sahih (good and authentic).

Sila narrates: We were present with Sayyiduna Ammar (may Allah be pleased with him) when roasted goat meat was brought for him, and he told us to eat. One person withdrew, so he (Ammar) said: "Whoever fasts on the day when there is doubt about (the beginning of) Ramadan, he has disobeyed Sayyiduna Abu al-Qasim (the Prophet Muhammad, peace and blessings be upon him)." This hadith is Hasan Sahih, and all the narrators of this hadith are trustworthy.

Sayyiduna Abu Hurairah (may Allah be pleased with him) narrates: The Noble Prophet (peace and blessings be upon him) forbade fasting on six days (the day about which there is doubt), the day of Eid al-Fitr, the day of Eid al-Adha, and the days of Tashreeq. Among the narrators of this hadith, other narrators are more reliable than Waqidi.

Abdullah bin Abbas (may Allah be pleased with them both) narrates: There was a difference among the people regarding the sighting of the Ramadan moon. Some said: It will be seen today, others said: It will be seen tomorrow. A Bedouin came to the Prophet (peace be upon him) and said: I have seen the moon. The Prophet (peace be upon him) asked: "Do you bear witness that there is no deity except Allah and that Muhammad (peace be upon him) is the Messenger of Allah?" He replied: Yes! So the Prophet (peace be upon him) ordered Bilal (may Allah be pleased with him) to announce among the people that they should begin fasting. The Prophet (peace be upon him) said: "Begin fasting upon seeing it (the moon) and end fasting upon seeing it. If clouds cover you, then complete the count of thirty days, begin fasting, and do not fast a day before it." This narration is also transmitted with some other chains. Some narrators have also transmitted this narration as a mursal narration.

Abdullah bin Abbas (may Allah be pleased with them) narrates: A man came to the Prophet (peace be upon him) and said: I have seen the moon. The Prophet (peace be upon him) asked:“Do you bear witness that there is no deity except Allah and that I am the Messenger of Allah?”He replied: Yes! The Prophet (peace be upon him) said:“O Bilal! Announce among the people that they should fast tomorrow.”

Abdullah bin Abbas (may Allah be pleased with them both) narrates: A Bedouin came to the service of the Prophet Muhammad (peace be upon him) and said: I have seen the moon. The Prophet (peace be upon him) said: "Do you bear witness that there is no deity except Allah and that I am the Messenger of Allah?" He replied: Yes! The Prophet (peace be upon him) said: "O Bilal! Announce among the people that they should fast tomorrow." The meaning of this hadith is close to the meaning of the previous narration.
