Jabir b. 'Abdullah reported that Allah's Messenger sent on in expedition a detachment consisting of three hundred (persons) and appointed Abu 'Ubaida b. Jarrah as their chief. Their provisions ran short: 'Abu 'Ubaida collected their provisions in the provision bag. and he fed us (for some time). Later on when the provisions ran short he gave us one date every day.

وَحَدَّثَنِي مُحَمَّدُ بْنُ حَاتِمٍ، حَدَّثَنَا عَبْدُ الرَّحْمَنِ بْنُ مَهْدِيٍّ، عَنْ مَالِكِ بْنِ أَنَسٍ، عَنْ أَبِي نُعَيْمٍ، وَهْبِ بْنِ كَيْسَانَ أَنَّ جَابِرَ بْنَ عَبْدِ اللَّهِ، أَخْبَرَهُ قَالَ بَعَثَ رَسُولُ اللَّهِ صلى الله عليه وسلم سَرِيَّةً ثَلاَثَمِائَةٍ وَأَمَّرَ عَلَيْهِمْ أَبَا عُبَيْدَةَ بْنَ الْجَرَّاحِ فَفَنِيَ زَادُهُمْ فَجَمَعَ أَبُو عُبَيْدَةَ زَادَهُمْ فِي مِزْوَدٍ فَكَانَ يُقَوِّتُنَا حَتَّى كَانَ يُصِيبُنَا كُلَّ يَوْمٍ تَمْرَةٌ ‏.‏
