If eating unexpectedly

Narrated Jabir ibn Abdullah:

The Messenger of Allah ﷺ came out from the valley of a mountain where he had eased himself. There were some dried dates on a shield before us. We called him and he ate with us. He did not touch water.

حَدَّثَنَا أَحْمَدُ بْنُ أَبِي مَرْيَمَ، حَدَّثَنَا عَمِّي، - يَعْنِي سَعِيدَ بْنَ الْحَكَمِ - حَدَّثَنَا اللَّيْثُ بْنُ سَعْدٍ، أَخْبَرَنِي خَالِدُ بْنُ يَزِيدَ، عَنْ أَبِي الزُّبَيْرِ، عَنْ جَابِرِ بْنِ عَبْدِ اللَّهِ، أَنَّهُ قَالَ أَقْبَلَ رَسُولُ اللَّهِ ﷺ مِنْ شِعْبٍ مِنَ الْجَبَلِ وَقَدْ قَضَى حَاجَتَهُ وَبَيْنَ أَيْدِينَا تَمْرٌ عَلَى تُرْسٍ أَوْ حَجَفَةٍ فَدَعَوْنَاهُ فَأَكَلَ مَعَنَا وَمَا مَسَّ مَاءً .
