The reciter: Qutaybah ibn Sa'id narrated to us, and Layth ibn Sa'd narrated to us. And Muhammad ibn Rumh narrated to us, and al-Layth informed us, from Abu al-Zubayr, from Jabir, who said:
We were one thousand and four hundred on the day of al-Hudaybiyyah, so we pledged allegiance to him, and 'Umar was holding his hand under the tree, which was a tamarisk, and he said: We pledged allegiance to him on the condition that we would not flee, and we did not pledge allegiance to him on the condition of death.
كُنَّا يَوْمَ الْحُدَيْبِيَةِ أَلْفًا وَأَرْبَعَ مِائَةً، فَبَايَعْنَاهُ وَعُمَرُ آخِذٌ بِيَدِهِ تَحْتَ الشَّجَرَةِ، وَهِيَ سَمُرَةٌ، وَقَالَ : بَايَعْنَاهُ عَلَى أَنْ لَا نَفِرَّ، وَلَمْ نُبَايِعْهُ عَلَى الْمَوْتِ Sunan ad-Darimi 17:19.
