On the authority of Jabir, from the Messenger of Allah, peace and blessings be upon him, that he said: "None of those who pledged allegiance under the tree will enter the Fire."(1)

4654 - Musa ibn Isma'il narrated to us, Hammad ibn Salama narrated to us (another chain).
And Ahmad ibn Sinan al-Qattan narrated to us, Yazid ibn Harun narrated to us, Hammad ibn Salama informed us, on the authority of 'Asim, on the authority of Abu Salih,
on the authority of Abu Hurayra, who said: The Messenger of Allah, peace and blessings be upon him, said — Musa said: "Perhaps Allah" and Ibn Sinan said: "Allah looked upon the people of Badr and said: 'Do whatever you wish, for I have forgiven you.'"(2)

(1) Its chain of transmission is sound. Abu al-Zubayr — who is Muhammad ibn Muslim ibn Tadrus al-Makki — explicitly stated that he heard it directly, as recorded by Muslim and others, thus removing any suspicion of tadlis (concealment). Moreover, the narrator from him here is al-Layth — who is Ibn Sa'd — and he only transmitted from him what was established to him as heard directly from Jabir, as Ibn Hazm narrated from al-Layth himself that he said this.
Al-Tirmidhi (4197) and al-Nasa'i in "al-Kubra" (11444) also transmitted it from Qutayba ibn Sa'id alone, with this chain of transmission. Al-Tirmidhi said: This is a good and sound hadith.
Muslim (2496) also transmitted it via Ibn Jurayj: Abu al-Zubayr informed me that he heard Jabir ibn 'Abdullah say: Umm Mubashshir told me that she heard the Prophet, peace and blessings be upon him, say in the presence of Hafsa: "None of the people of the tree — none of those who pledged allegiance under it — will enter the Fire, Allah willing." She said: "Yes, O Messenger of Allah," and he rebuked her. Hafsa then said: {And there is none of you but will pass over it} [Maryam: 71]. The Prophet, peace and blessings be upon him, said: "Allah, Mighty and Majestic, has said: {Then We will save those who feared Allah and leave the wrongdoers within it, on their knees} [Maryam: 72]."
Ibn Majah (4281) also transmitted it via al-A'mash, from Abu Sufyan Talha ibn Nani', from Jabir, from Umm Mubashshir, from Hafsa. There is disagreement regarding this chain from al-A'mash, as we have explained in "Musnad Ahmad" (26440).
It is also found in "Musnad Ahmad" (14778) and "Sahih Ibn Hibban" (4802).

(2) Sound through other supporting narrations. This chain is good on account of 'Asim — who is Ibn Abi al-Nujud — and Abu Salih: he is Dhakwan al-Samman. The sounder of these two narrations is the narration of Musa ibn Isma'il.
