Samʿān, from Ibrāhīm ibn ʿUbayd ibn Rifāʿah, from ʿAbd al-Raḥmān ibn Abī Laylā, from Ḥudhayfah ibn al-Yamān, to the same effect. Its narrators are trustworthy, apart from Ibn Samʿān—whose name was ʿAbd Allāh ibn Ziyād. Mālik, Ibn Maʿīn, and others said: “A liar.” Thus, reliance is upon the first chain; I mentioned this one only to clarify its status.
It also has a corroborating report from Abū Hurayrah: the Prophet, may Allah bless him and grant him peace, met Ḥudhayfah and wished to shake his hand, but Ḥudhayfah drew away … the hadith, to the same effect. Al-Haythamī said: “Al-Bazzār narrated it, and its chain includes Muṣʿab ibn Thābit. Ibn Ḥibbān declared him trustworthy, whereas the majority deemed him weak.”
527 — “The people of Yemen have arrived; they are more tender-hearted than you. (Anas said:) They were the first to introduce handshaking.”
Al-Bukhārī narrated it in al-Adab al-Mufrad (967), and Aḥmad (3:212, 251), through several chains from Ḥammād ibn Salamah, from Ḥumayd, from Anas ibn Mālik, who said: “When the people of Yemen arrived, the Prophet, may Allah bless him and grant him peace, said …” The wording is al-Bukhārī’s, without the addition. Its apparent meaning is that the statement, “They were …,” forms part of the hadith attributed to the Prophet. Al-Ḥāfiẓ followed this understanding in al-Fatḥ (11:46), saying, after attributing it to al-Bukhārī: “With an authentic chain through Ḥumayd …” In Jāmiʿ Ibn Wahb, through this same chain, it reads: “They were the first to openly practise handshaking.”
