Kuraib reported that 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 Madinah at the end of the month.'Abdullah bin 'Abbas (RA) asked me (about the new moon of Ramadan) and said: When did you see it? I said.: We saw it on the night of Friday. He said: (Did) you see it yourself? -I said: Yes, and the people also saw it and they observed fast and Mu'awiyah also observed fast, whereupon he said: But we saw it on Saturday night. So we would continue to observe fast till we complete thirty (lasts) 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 ( صلی اللہ علیہ وسلم ) has commanded us. Yahya bin Yahya was in doubt (whether the word used in the narration by Kuraib) was Naktafi or Taktafi.
