حَدَّثَنَا مُوسَی بْنُ إِسْمَعِيلَ حَدَّثَنَا إِسْمَعِيلُ يَعْنِي ابْنَ جَعْفَرٍ أَخْبَرَنِي مُحَمَّدُ بْنُ أَبِي حَرْمَلَةَ أَخْبَرَنِي کُرَيْبٌ أَنَّ أُمَّ الْفَضْلِ ابْنَةَ الْحَارِثِ بَعَثَتْهُ إِلَی مُعَاوِيَةَ بِالشَّامِ قَالَ فَقَدِمْتُ الشَّامَ فَقَضَيْتُ حَاجَتَهَا فَاسْتَهَلَّ رَمَضَانُ وَأَنَا بِالشَّامِ فَرَأَيْنَا الْهِلَالَ لَيْلَةَ الْجُمُعَةِ ثُمَّ قَدِمْتُ الْمَدِينَةَ فِي آخِرِ الشَّهْرَ فَسَأَلَنِي ابْنُ عَبَّاسٍ ثُمَّ ذَکَرَ الْهِلَالَ فَقَالَ مَتَی رَأَيْتُمْ الْهِلَالَ قُلْتُ رَأَيْتُهُ لَيْلَةَ الْجُمُعَةِ قَالَ أَنْتَ رَأَيْتَهُ قُلْتُ نَعَمْ وَرَآهُ النَّاسُ وَصَامُوا وَصَامَ مُعَاوِيَةُ قَالَ لَکِنَّا رَأَيْنَاهُ لَيْلَةَ السَّبْتِ فَلَا نَزَالُ نَصُومُهُ حَتَّی نُکْمِلَ الثَّلَاثِينَ أَوْ نَرَاهُ فَقُلْتُ أَفَلَا تَکْتَفِي بِرُؤْيَةِ مُعَاوِيَةَ وَصِيَامِهِ قَالَ لَا هَکَذَا أَمَرَنَا رَسُولُ اللَّهِ صَلَّی اللَّهُ عَلَيْهِ وَسَلَّمَ
سنن ابودوٗد · Hadith 2332
Narrated Kuraib: That Umm al-Fadl, daughter of al-Harith, sent him to Mu'aqiyah in Syria. He said: I came to syria and performed her work. The moon of Ramadan appeared while I was in Syria. We sighted the moon on the night of Friday. When I came to Median towards the end of the month (of Ramadan), Ibn Abbas asked me about the moon. He said: When did you sight the moon ? I said: I sighted it on the night of Friday. He asked: Did you sight it yourself ? I said: Yes, and the people sighted it. They fasted and Muawiyah also fasted. He said: But we sighted it on the night of saturday. Since then we have been fasting until we complete thirty days or we sight it. Then I said: Are the sighting of the moon by Muawiyah and his fasts not sufficient for us? He replied: No. The Messenger of Allah ﷺ commanded us to do so.
