The Messenger of Allah ﷺ commanded us to sacrifice one sheep as the aqiqah for a Jariya and two sheep for a boy, and he commanded us regarding the firstborn offering of livestock to give one sheep for every five sheep.
أمرنا رسول الله ﷺ أن نعق عن الجارية شاة، وعن الغلام شاتين، وأمرنا بالفرع من كل خمس شياه شاة.
Ahmad (25250) and Ibn Abu Shayba (24789) both narrated it from Affan, from Hammad, who said, Abdullah bin Uthman bin Khuthaym told us, from Yusuf bin Mahak, from Hafsa bint Abdul-Rahman, from Ayesha, and he related it. Its isnad is hasan due to the discussion regarding Ibn Khuthaym, though his hadith is hasan, and the rest of its narrators are reliable. Affan is Ibn Muslim Saffar, Hammad is Ibn Salama, and Hafsa is the daughter of Abdul-Rahman bin Abu Bakr Siddiq.However, there is disagreement about his wording, "for every five," regarding Hammad. Affan narrated it from him this way, and Abdul-Samad bin Abdul-Warith Anbari also corroborated him. Imam Ahmad (26134) and Ishaq bin Rahawayh (1032) narrated it from him, while Musa bin Ismail Tabuzaki differed from them both, narrating it from Hammad with his isnad but saying, "for every fifty." Abu Dawud (2833) recorded it in abridged form with the wording, "The Messenger of Allah ﷺ commanded us, one sheep for every fifty sheep," without mentioning the firstling sacrifice or the newborn sacrifice.Ibn Jurayj likewise narrated it from Ibn Khuthaym, and there is disagreement about his narration. Abdul-Razzaq (7997) narrated it, and Bayhaqi (9/312) through his route, saying, Ibn Jurayj informed us, Abdullah bin Uthman bin Khuthaym informed me with his isnad, from Ayesha, who said, "The Messenger of Allah ﷺ commanded that one animal be offered as a firstling sacrifice for every fifty." Bayhaqi said, "This is what is in my book, but in the narration of Hajjaj bin Muhammad and others from Ibn Jurayj it reads, 'one for every five.'" I say, this is the wording of Ishaq bin Rahawayh in his Musnad (1034), from Abdul-Razzaq, [who said] Ibn Jurayj narrated it to us with this, then Ishaq explained it by saying, "one for every five sheep." As for the narration of Hajjaj bin Muhammad (that is, Masissi), Hakim recorded it (4/235-236) and said, "Its isnad is sahih."Abu Yaala Mawsili (4509) narrated it through the route of Yahya bin Salim, from Ibn Khuthaym with his isnad, from Ayesha, that she heard the Messenger of Allah ﷺ commanding one firstling sacrifice for every five sheep. Yahya bin Salim is Taifi, and although there is some criticism of his memory, he had mastered the hadith of Ibn Khuthaym because it was recorded in a book he possessed, as Imam Ahmad said in al-Ilal (3150). This shows that most said "five," and whoever said "fifty," it is possible that this was a scribal error by some of the narrators or copyists. And Allah knows best.On this topic there is also a narration from Abu Razeen Laqeet bin Amir Aqeeli, who said, I said, "O Messenger of Allah, we used to slaughter sacrifices during the pre-Islamic era in Rajab, and we would eat and feed whoever came to us." The Messenger of Allah ﷺ said, "There is no harm in it." Waki bin Adas said, "So I do not give it up." Nasai (4233) and Ahmad (16202) narrated it, and Ibn Hibban (5891) graded it sahih, through the route of Abu Awana (that is, Waddah bin Abdullah Yashkuri), from Yaala bin Ata, from Waki bin Adas, from his uncle Abu Razeen, and he related it. Its narrators are reliable except for Waki bin Adas, also said to be Ibn Hadas with a ha, Aqeeli Taifi, whom no one deemed reliable except Ibn Hibban, who mentioned him among the reliable narrators according to his usual practice, and no one is known to have narrated from him except Yaala bin Ata, so he is closer to being unknown. Dhahabi said in al-Mizan, "He is not known."On this topic there is also a narration from Harith bin Amr, that he met the Messenger of Allah ﷺ during the Farewell Pilgrimage. I said, "May my father be sacrificed for you, O Messenger of Allah, ask forgiveness for me." He said, "May Allah forgive you." He said, and he was on his she-camel Adhba. He said, so I pushed forward on the other side, hoping he would single me out apart from the people. I said, "Ask forgiveness for me." He said, "May Allah forgive you." A man said, "O Messenger of Allah, what about the firstling sacrifices and the Rajab sacrifices?" He said, "Whoever wishes may offer a firstling sacrifice, and whoever wishes may not, whoever wishes may offer a Rajab sacrifice, and whoever wishes may not, a sacrificial offering may be made from sheep." Then he said, "Indeed, your blood and your property are forbidden to one another, like the sanctity of this day of yours, in this land of yours."Imam Ahmad (15972) narrated it, and this is his wording. Nasai (4226, 4227), Tabarani in al-Kabir (3350), and Hakim (4/236) narrated it in abridged form, all through routes from Yahya bin Zurara bin Kareem bin Harith bin Amr Bahili, who said, I heard my father mention that he heard his grandfather Harith bin Amr narrating, and he related the hadith. Yahya bin Zurara was not deemed reliable by anyone other than Ibn Hibban, so Hafiz said in Taqrib, "Acceptable." I say, this is indeed the case, because he was corroborated. Tabarani in al-Kabir (3351), Hakim (4/232), and Bayhaqi (5/28) all narrated it through the route of Abdul-Warith, from Utba bin Abdul-Malik Sahmi, from Zurara, with his isnad, similarly.Tabarani also recorded it (3352) through another route, from Sahl bin Husayn Bahili, from Zurara bin Kareem, from Harith bin Amr Sahmi, that he came to the Messenger of Allah ﷺ during the Farewell Pilgrimage, while he was on his she-camel Adhba, and Harith was a large man, so Harith got down to him, and drew near him until his face was level with the knee of the Messenger of Allah ﷺ, and the Prophet of Allah ﷺ reached down and wiped Harith's face, and the glow remained on Harith's face until he died. Harith said to him, "O Prophet of Allah, pray to Allah for me." He said, "O Allah, forgive us," and he related the rest similarly to the hadith of Abdul-Warith. End.Hakim said, "This is a sahih hadith which the two of them did not record." I say, in the isnad is Zurara bin Kareem, whom no one deemed reliable except Ibn Hibban, who is known for deeming reliable those in whom no fault has been identified. It is said that he had seen the Prophet, but this is not correct, as Ibn Hajar concluded in Isaba. Ibn Hibban said, "Whoever says that he was a companion has erred."See further, Minna Kubra (4/550).
