[Machine] That Umar has permitted the testimony of one man regarding the sighting of the crescent moon during the festivals of Eid al-Fitr or Eid al-Adha. Abu Bakr ibn al-Harith informed us that Ali ibn Umar al-Hafith narrated that Abu Bakr al-Naysaburi said Muhammad ibn Ali al-Warraq asked Abu Nuaim if Ibn Abi Layla heard from Umar. He replied, "I do not know." Muhammad ibn Ali said, "I asked Yahya ibn Ma'in if Ibn Abi Layla heard from Umar, but he did not confirm it." Ali ibn Abdu al-A'la ibn Amir al-Tha'labi said other than him confirmed it. The hadith of Abu Wael is the most authentic in its chain of narration from Umar.
أَنَّ عُمَرَ ؓ أَجَازَ شَهَادَةَ رَجُلٍ وَاحِدٍ فِي رُؤْيَةِ الْهِلَالِ فِي فِطْرٍ أَوْ أَضْحَى وَأَخْبَرَنَا أَبُو بَكْرِ بْنُ الْحَارِثِ أَنْبَأَ عَلِيُّ بْنُ عُمَرَ الْحَافِظُ ثنا أَبُو بَكْرٍ النَّيْسَابُورِيُّ قَالَ قَالَ مُحَمَّدُ بْنُ عَلِيٍّ الْوَرَّاقُ قُلْتُ لِأَبِي نُعَيْمٍ سَمِعَ ابْنُ أَبِي لَيْلَى مِنْ عُمَرَ؟ قَالَ لَا أَدْرِي قَالَ مُحَمَّدُ بْنُ عَلِيٍّ قُلْتُ لِيَحْيَى بْنِ مَعِينٍ سَمِعَ ابْنُ أَبِي لَيْلَى مِنْ عُمَرَ؟ فَلَمْ يُثْبِتْ ذَلِكَ قَالَ عَلِيٌّ عَبْدُ الْأَعْلَى هُوَ ابْنُ عَامِرٍ الثَّعْلَبِيُّ غَيْرُهُ أَثْبَتُ مِنْهُ وَحَدِيثُ أَبِي وَائِلٍ أَصَحُّ إِسْنَادًا عَنْ عُمَرَ مِنْهُ
