حَدَّثَنَا أَحْمَدُ بْنُ مَنِيعٍ، قَالَ‏:‏ حَدَّثَنَا عَبَّادُ بْنُ الْعَوَّامِ، قَالَ‏:‏ أَخْبَرَنَا الْحَجَّاجُ وَهُوَ ابْنُ أَرْطَاةَ، عَنْ سِمَاكِ بْنِ حَرْبٍ، عَنْ جَابِرِ بْنِ سَمُرَةَ، قَالَ‏:‏ كَانَ فِي سَاقَيْ رَسُولِ اللهِ صلى الله عليه وسلم، حُمُوشَةٌ، وَكَانَ لا يَضْحَكُ إِلا تَبَسُّمًا، فَكُنْتُ إِذَا نَظَرْتُ إِلَيْهِ، قُلْتُ‏:‏ أَكْحَلُ الْعَيْنَيْنِ، وَلَيْسَ بِأَكْحَلَ‏.‏‏.‏

'Amir ibn Sa'd said

“Sa'd [Ibn Abi Waqqas] said: ‘I had seen the Prophet (Allah bless him and give him peace) laugh at the Battle of the Trench, so hard that his molar teeth became apparent.’ I said: ‘How was his laughter?’ He said: ‘There was a man holding a shield while Sa'd was shooting, and the man was saying such-and-such and such-and-such, with the shield covering his forehead. Sa'd therefore aimed an arrow at him and shot it when he raised his head, so it did not miss this part of him — meaning his forehead — and the man toppled over and kicked up his foot. The Prophet (Allah bless him and give him peace) then laughed so much that his molar teeth became apparent.’ I asked: ‘What made him laugh?’ He replied: ‘What he did to the man!”
