Hadith 678

وعن علي بن أبي طالب رضي الله تعالى عنه قال: أمرني رسول الله صلى الله عليه وآله وسلم أن أبيع غلامين أخوين ،‏‏‏‏ فبعتهما ،‏‏‏‏ ففرقت بينهما ،‏‏‏‏ فذكرت ذلك للنبي لى الله عليه وآله وسلم فقال:« أدركهما فارتجعهما ،‏‏‏‏ ولا تبعهما إلا جميعا». رواه أحمد ،‏‏‏‏ ورجاله ثقات ،‏‏‏‏ و قد صححه ابن خزيمة وابن الجارود وابن حبان والحاكم والطبراني وابن القطان.
Narrated 'Ali bin Abu Talib (RA): Allah's Messenger (ﷺ) commanded me to sell two youths who were brothers. I sold them and separated them (by selling them to different people). When I made mention of that to the Prophet (ﷺ), he said, "Find them and get them back, and do not sell them except that they are together." [Reported by Ahmad, and the narrators of his chain are reliable. Indeed Ibn Khuzaimah, Ibn al-Jarud, Ibn Hibban, al-Hakim, at-Tabarani and Ibn Qattan graded it Sahih (authentic)].

«أخرجه الترمذي، البيوع، باب ما جاء في كراهية الفرق بين الأخوين، حديث:1284، وابن ماجه، التجارات، حديث:2249، وأحمد:1 /97، 126، والحاكم:2 /55.* وقال أبوداود، حديث"2696 "ميمون لم يدرك عليًا".»©Explanation:
➊ The aforementioned narration has been declared weak in its chain (sanad) by our esteemed researcher, whereas other scholars have graded it as authentic (sahih) or sound (hasan). The researchers of Musnad Ahmad have classified it as hasan li-ghayrihi (sound due to supporting narrations). Therefore, despite the narration being weak in its chain, it is actionable and authoritative due to other supporting evidences and corroborations. For further details, see: (al-Mawsu‘ah al-Hadithiyyah, Musnad al-Imam Ahmad: 2/155).

➋ The previous hadith indicates the prohibition of separating a mother and her child, whether that separation occurs through sale, gift, or by means of deception or any other form.

➌ The word "mother" also includes the "father," meaning that separation should not occur from the mother nor from the father. And this hadith indicates the prohibition of separation and division between siblings, and by analogy (qiyas), other close relatives (dhawi al-arham) have also been included with them. However, Imam al-Shawkani rahimahullah is of the opinion that including other close relatives (dhawi al-arham) in this ruling is questionable, because the hardship and distress caused by their separation is not the same as that which results from separating a mother and child or between brothers. Therefore, due to the clear difference between the two, one should not combine one with the other, and should restrict oneself to the explicit text.

➍ It should also be known that the prohibition of separation is specific to a young child. When is separation of an older child permissible? There is a difference of opinion on this. According to the evidence, the preferred view is that when a boy or girl reaches puberty (bulugh), then separation is not prohibited.
