Ismāʿīl, from Qays, from him; whereas others among Ismāʿīl’s students—such as ʿAbdah ibn Sulaymān, Wakīʿ, Hushaym, and Marwān—reported it as mursal. Al-Ḥajjāj ibn Arṭāh concurred with him in reporting it with a connected chain, from Ismāʿīl, but al-Ḥajjāj is weak. Al-Bukhārī and others preferred the mursal version. Ḥafṣ ibn Ghiyāth differed from all of them, narrating it from Ismāʿīl, from Qays, from Khālid ibn al-Walīd. Al-Ṭabarānī recorded it.”
It is also found in Abū Dāwūd’s Book of Jihad. Al-Ṭabarānī likewise recorded it in al-Muʿjam al-Kabīr (vol. 1, folio 109a), in the manuscript of the al-Ẓāhiriyyah Library (no. 282, hadith), from Abū Muʿāwiyah through this chain. A hadith with a similar meaning states: “Allah does not accept any deed from a polytheist after he accepts Islam unless he leaves the polytheists and joins the Muslims.” It has been mentioned in its proper place.
637 — “No two people love one another for the sake of Allah, Mighty and Majestic, or through Islam, and then become separated except because of a sin committed by one of them.”
Al-Bukhārī recorded it in al-Adab al-Mufrad (401), through the route of Sinān ibn Saʿd, from Anas, that the Messenger of Allah, peace and blessings be upon him, said this.
I say: Its chain of transmission is good. Its narrators are trustworthy and are among the narrators of the two Shaykhs, apart from Sinān ibn Saʿd—who is also called Saʿd ibn Sinān. Al-Ḥāfiẓ said: “He is truthful and has some solitary narrations.”
I say: This is not one of the reports in which he was alone, for a number of Companions other than Anas narrated it. Among them was ʿAbdullāh ibn ʿUmar, from whom it is reported that the Prophet, peace and blessings be upon him, used to say this in a hadith.
Aḥmad recorded it (2/68) through the route of Ibn Lahīʿah, from Khālid ibn Abī ʿImrān, from Nāfiʿ, from Ibn ʿUmar. Its narrators are trustworthy, except that Ibn Lahīʿah had poor retention; thus, his hadith may be cited as corroborative evidence.
