Husayn bin Harith Jadali narrated that the governor of Mecca delivered a sermon and then said, "The Messenger of Allah ﷺ charged us to perform the rites upon sighting the moon. If we do not see it ourselves but two trustworthy witnesses testify to having seen it, we perform the rites based on their testimony."I asked Husayn bin Harith, "Who was the governor of Mecca?"He replied, "I do not know."Then he met me later and said, "He was Harith bin Hatib, the brother of Muhammad bin Hatib."Then the governor said, "Among you is one who knows Allah and His Messenger better than I do, and he witnessed this directly from the Messenger of Allah ﷺ," and he gestured with his hand toward a man.Husayn said, I asked an elderly man beside me, "Who is this man the governor pointed to?"He answered, "This is Abdullah bin Umar," and he spoke truly. He was indeed more knowledgeable about Allah than the governor.Then Ibn Umar said, "This is what the Messenger of Allah ﷺ commanded us to do."
حدثنا حسين بن الحارث الجدلي، ان أمير مكة خطب، ثم قال: عهد الينا رسول الله ﷺ ان ننسك للرؤية، فان لم نره وشهد شاهدا عدل نسكنا بشهادتهما، فسألت الحسين ابن الحارث: من أمير مكة؟ قال: لا ادري، ثم لقيني بعد قال: هو الحارث بن حاطب اخو محمد بن حاطب. ثم قال الامير: ان فيكم من هو اعلم بالله ورسوله مني. وشهد هذا من رسول الله ﷺ وامأ بيده الي رجل. قال الحسين: فقلت لشيخ الي جنبي: من هذا الذي امأ اليه الامير؟ قال: هذا عبد الله بن عمر، وصدق. كان اعلم بالله منه. فقال: بذلك امرنا رسول الله ﷺ.
Abu Dawud (2338) narrated it from Muhammad bin Abdul-Rahim Abu Yahya Bazzar, who said, Saeed bin Sulayman narrated to us, who said, Abbad narrated to us, from Abu Malik Ashjai, who said, Husayn bin Harith Jadali narrated to us, and he mentioned it. Bayhaqi narrated it (4/248) through his route. Daraqutni narrated it (2191, 2192), abridged and in full, through two other routes, from Saeed bin Sulayman, and Bayhaqi extracted it from one of these two routes.Daraqutni said, "This is a connected, sahih isnad." I say, this is as he said, except that Husayn bin Harith Jadali did not reach the rank of the trustworthy and precise narrators, though he is not unknown as Ibn Hazm claimed in Muhalla (6/238), for a number of narrators transmitted from him. Ibn Madini said, "He was well known," and Ibn Hibban mentioned him in Thiqat (4/155). The conclusion regarding him, as Ibn Hajar said, is that he is "truthful."Ahmad narrated it in his Musnad (18895) from Husayn bin Harith Jadali, who said, Abdul-Rahman bin Zayd bin Khattab gave a sermon on the day about which there was doubt, and said, "I have sat with the companions of the Messenger of Allah ﷺ and asked them, and they told me that the Messenger of Allah ﷺ said, 'Fast upon sighting it and break the fast upon sighting it, and perform the rites for it. If it is obscured from you, then complete thirty days. And if two Muslim witnesses testify, then fast and break the fast.'" However, it is daif. He narrated it from Yahya bin Zakariya, who said, Hajjaj informed us, from Husayn bin Harith Jadali, and he mentioned it.Daraqutni narrated it (2193) through the hadith of Yazid bin Harun, who said, Hajjaj narrated to us with his isnad. Hajjaj here is Ibn Artah, who is daif. Nasai narrated it (2116) through the route of Yahya bin Zakariya bin Abu Zaida, from Husayn bin Harith Jadali, without mentioning "Hajjaj" between them. Ibn Abdul-Hadi said in Tanqih Tahqiq (3/216), "It seems to be an error." Mizzi said, "The correct view is that he should be mentioned."I say, the error in this hadith may be from Hajjaj, for the correct view is that Husayn bin Harith narrates from the governor of Makkah, whereas Hajjaj made him narrate from Abdul-Rahman bin Zayd bin Khattab, or that is confirmed through two routes, but one does not feel at ease regarding Hajjaj.On this subject there is also what was reported from Shaqiq, who said, "A letter from Umar came to us while we were at Khaniqin. In his letter he said, 'The crescents vary, some larger than others, so if you see the crescent moon during the day, do not break your fast until two witnesses testify.'" Daraqutni narrated it (2196) from Abu Bakr Nisaburi, who said, Ali bin Harb and Saadan bin Nasr narrated to us, they said, Abu Muawiya narrated to us, who said, Amash narrated to us, from Shaqiq, and he mentioned it.Shuba narrated it from Amash, and he said, "If you see the crescent moon at the beginning of the day, do not break the fast until two witnesses testify that they saw it yesterday." Daraqutni said, this has a more sahih isnad than the hadith of Ibn Abu Layla, and Mansur corroborated Amash, which we will record after this. Then he cited the hadith of Mansur through several routes from him. Bayhaqi narrated it (4/248) through the route of Shuba, from Amash, with the same wording, similarly. He said, "This is a report that is sahih from Umar ."As for the report of Ibn Abu Layla to which Daraqutni referred, he narrated it himself (2198), and Bayhaqi narrated it from him (4/249), from Abu Bakr Nisaburi, who said, Muhammad bin Ali Warraq narrated to us, who said, Ubaydullah bin Musa narrated to us, who said, Israil informed us, from Abdul-Ala, from Ibn Abu Layla, who said, "I was with Umar, and a rider came to him claiming that he had seen the crescent moon, so he ordered the people to break their fast."Muhammad bin Ali said, I said to Abu Naeem, "Did Ibn Abu Layla hear from Umar?" He said, "I do not know." Muhammad bin Ali said, I said to Yahya bin Main, "Did Ibn Abu Layla hear from Umar?" But that was not confirmed. Abdul-Ala is Ibn Amir Thalabi, and others are more reliable than him. The hadith of Abu Waail has a more sahih isnad from Umar than this one. Amash and Mansur narrated it from Abu Waail.Bayhaqi added, from Abbas bin Muhammad Duri, who said, Yahya bin Main was asked about Abdul-Rahman bin Abu Layla narrating from Umar, and he said, "He did not see him." I said to him, "What about the hadith that is narrated, 'We were with Umar looking for the crescent moon'?" He said, "It is nothing." End.Ahmad narrated it (307), and Bayhaqi (4/248), from Yazid bin Harun, who said, Warqa bin Umar informed us, from Abdul-Ala Thalabi, from Abdul-Rahman bin Abu Layla, who said, "I was with Bara bin Azib and Umar bin Khattab at Baqi, looking at the crescent moon, when a rider approached. Umar met him and said, 'Where have you come from?' He said, 'From the west.' Umar said, 'Did you see the crescent moon?' He said, 'Yes.' Umar said, 'Allah is greatest, one man is sufficient for the Muslims.' Then Umar stood, performed wudu, wiped over his socks, then prayed Maghrib, then said, 'This is how I saw the Messenger of Allah ﷺ do it.'" Its isnad is daif because of Abdul-Ala and Abdul-Rahman bin Abu Layla, as mentioned before.The jurisprudence of this chapter, the majority of the scholars used the hadiths of this chapter as evidence that the crescent moon of Shawwal is not established except by the testimony of two just witnesses. Ibn Qayyim said in Zad (2/49-50), "It was part of his ﷺ guidance to command the people to fast upon the testimony of a single Muslim man, and to end it upon the testimony of two."Nawawi said in Majmu (2816), "This is our school of thought, and all the scholars held it except Abu Thawr. Our companions related from him that he accepts a single just witness for Shawwal, just as for the crescent moon of Ramadan. Ibn Munzir related this from Abu Thawr and a group of the people of hadith. Imam Haramayn said, 'The author of Taqrib said, "If I were to hold the view that Abu Thawr held, I would not be far off the mark."'" End.
