Kuraib narrated that Umm Al-Fadl sent him to Muawiyah in Ash-Sham. He said: “I came to Ash-Sham and completed her errand. Then the new crescent of Ramdan sighted while I was in Ash-Sham. I saw the new crescent on the night of Friday, then I came to Al-Madinah at the end of the month. ‘Abdullah bin ‘Abbas asked me about the sighting of the moon and said: ‘When did you see it?’ I said: ‘We saw it on the night of Friday.’ He said: ‘You saw it on the night of Friday?’ I said: ‘Yes, and the people saw it and started fasting, and so did Muawiyah.’ He said: ‘But we saw it on the night of Saturday, so we will continue fasting until we have completed thirty days or we see it.’ said: ‘Will you not be content with the sighting of Muawiyah and his companions?’ He said: ‘No; this is what the Messenger of Allah صلی اللہ علیہ وآلہ وسلم enjoined upon us.” (Sahih)
