On the authority of Ibn ʿAbbās, who said: The Messenger of Allah, peace and blessings be upon him, forbade breathing into the vessel or blowing into it. (1)

3729 — Ḥafṣ ibn ʿUmar narrated to us, Shuʿbah narrated to us, from Yazīd ibn Khumayr, from ʿAbdullāh ibn Busr — of the tribe of Banū Sulaym — who said: The Messenger of Allah, peace and blessings be upon him, came to my father and alighted with him. He presented food to him, and he mentioned ḥays that he brought to him. Then he brought him a drink, and he drank, then gave it to the one on his right. Then he ate dates, and he began to cast the pits on the back of his two fingers, the index and the middle. When he stood up, my father stood up and took hold of the reins of his mount, saying: Supplicate to Allah for me. He said: "O Allah, bless them in what You have provided them, and forgive them, and have mercy upon them." (2)

(1) Its chain of transmission is authentic. ʿAbd al-Karīm: he is Ibn Mālik al-Jazarī; Ibn ʿUyaynah: he is Sufyān.
It was also recorded by Ibn Mājah (3429) and al-Tirmidhī (1997) via the chain of Sufyān ibn ʿUyaynah, with this chain of transmission. Al-Tirmidhī said: A ḥasan ṣaḥīḥ ḥadīth. Ibn Mājah limited it to mentioning blowing into the vessel.
It was also recorded by Ibn Mājah (3288) via the chain of Sharīk ibn ʿAbdillāh al-Nakhaʿī, from ʿAbd al-Karīm al-Jazarī, with it, in the wording: The Messenger of Allah, peace and blessings be upon him, did not blow into food or drink, nor did he breathe into the vessel. And Sharīk is weak in memory.
It was also recorded by Ibn Mājah (3428) via the chain of Khālid al-Ḥadhāʾ, from ʿIkrimah, with it, in the wording: The Messenger of Allah, peace and blessings be upon him, forbade breathing into the vessel.
And it is in the Musnad of Aḥmad (1907), and the Ṣaḥīḥ of Ibn Ḥibbān (5316).

(2) Its chain of transmission is authentic.
It was also recorded by Muslim (2042), al-Tirmidhī (3893), and al-Nasāʾī in al-Kubrā (15051) and (10552) via multiple paths from Shuʿbah, with it.
It was also recorded by al-Nasāʾī (10050) via the path of Yaḥyā ibn Ḥammād, from Shuʿbah, from Yazīd ibn Khumayr, from ʿAbdullāh ibn Busr, from his father. Thus he added Busr to the chain and made it from his direct narration.
It was also recorded in similar form by al-Nasāʾī (6730) via the path of Ṣafwān ibn ʿAmr, and (6873) via the path of Muḥammad ibn Ziyād, both from ʿAbdullāh ibn Busr. =
