Kurayb said: Umm Fadl, daughter of Harith, sent him (Fadl, i.e. her son) to Mu'awiyah in Syria. I (Fadl) arrived in Syria, and did the needful for her. It was there in Syria that the month of Ramadan commenced. I saw the new moon (of Ramadan) on Friday. I then came back to Medina at the end of the month. Abdullah ibn Abbas asked me (about the new moon of Ramadan) and said: When did you see it? I said: We saw it on Friday night. He said: (Did) you see it yourself? I said: Yes, and the people also saw it so they observed fast and Mu'awiyah also observed fast. Thereupon he said: But we saw it on Saturday night. So we shall continue to observe the fast until we complete thirty (fasts) or we see it (the new moon of Shawwal). I said: Is the sighting of the moon by Mu'awiyah not valid for you? He said: No; this is how the Messenger of Allah (peace_be_upon_him) has commanded us. Yahya ibn Yahya was in doubt (whether the word used in the narration by Kurayb) was Naktafi or Taktafi.

Some of the people said: It was three nights old, and others (said) that it was two nights old. We then met Ibn Abbas and told him we had seen the new moon, but that some of the people said it was three nights old and others that it was two nights old. He asked on which night we had seen it; and when we told him we had seen it on such and such night, he said the Prophet of Allah (peace_be_upon_him) had said Verily Allah deferred it till the time it is seen, so it is to be reckoned from the night you saw it.

We were with Umar between Mecca and Medina so that we might begin to look for the new moon. I was a man with sharp eyesight, so I could see it, but none saw it except myself. I began to say to Umar: Don't you see it? But he could not see it. Thereupon Umar said: I shall soon be able to see it (when it shines more brightly). I lay in bed. He then mentioned to us of the people of Badr and said: Allah's Apostle (peace_be_upon_him) showed us one day before (the actual battle) the place of death of the people (participating) in (the Battle) of Badr and he was saying: This will be the place of death of so and so tomorrow, if Allah wills. Umar said: By Him Who sent him with truth, they did not miss the places (of their death) which Allah's Apostle (peace_be_upon_him) had indicated for them. Then they were all thrown in a well, one after another. Allah's Apostle (peace_be_upon_him) then went to them and said: O, so and so, the son of so and so; O so and so, the son of so and so, have you found what Allah and His Apostle (peace_be_upon_him) had promised you? I have, however, found absolutely true what Allah had promised me. Umar said: Allah's Apostle (peace_be_upon_him) said: How can you talk as bodies without souls in them. Thereupon he said: You cannot hear more distinctly than (they can) what I say, but with the exception that they have no power to make any reply.

He said, "What are they, Ibn Jurayj?" and he replied, "I have seen you touching only the two Yamani corners, I have seen you wearing hairless sandals. I have seen you using yellow dye, and, when you were at Makkah and everybody had started doing talbiyah after seeing the new moon, I saw that you did not do so until the eighth of Dhul-Hijjah." Abdullah ibn Umar replied, "As for the corners, I only ever saw the Messenger of Allah, may Allah bless him and grant him peace, touching the two Yamani corners. As for the sandals, I saw the Messenger of Allah, may Allah bless him and grant him peace, wearing hairless sandals and doing wudu in them, and I like wearing them. As for using yellow dye, I saw the Messenger of Allah, may Allah bless him and grant him peace, using it, and I also like to use it for dyeing things with.

He replied: I saw you touching only the two Yamani corners; and I saw you wearing shoes having no hair; I saw you dyeing in yellow colour; and I saw you wearing ihram on the eighth of Dhul-Hijjah, whereas the people had worn ihram when they sighted the moon. Abdullah ibn Umar replied: As regards the corners, I have not seen the Apostle of Allah (peace_be_upon_him) touching anything (in the Ka'bah) but the two Yamani corners. As for the tanned leather shoes, I have seen the Apostle of Allah (peace_be_upon_him) wearing tanned leather shoes, and he would wear them after ablution. Therefore I like to wear them. As regards wearing yellow, I have seen the Apostle of Allah (peace_be_upon_him) wearing yellow, so I like to wear with it.

The Prophet (peace_be_upon_him) said: The month consists of twenty-nine days, but do not fast till you sight it (the moon) and do not break your fast till you sight it. If the weather is cloudy, calculate it thirty days. When the twenty-ninth of Sha'ban came, Ibn Umar would send someone (who tried) to sight the moon for him. If it was sighted, then well and good; in case it was not sighted, and there was no cloud and dust before him (on the horizon), he would not keep fast the next day. If there appeared (on the horizon) before him cloud or dust, he would fast the following day. Ibn Umar would end his fasting alone with the people, and did not follow this calculation.
