Narrated Mahmud bin Ar-Rabi:

On whose face Allah's Apostle had thrown water from his mouth, the water having been taken from their well while he was still a young boy (who has not yet attained the age of puberty).

حَدَّثَنَا عَبْدُ الْعَزِيزِ بْنُ عَبْدِ اللَّهِ، حَدَّثَنَا إِبْرَاهِيمُ بْنُ سَعْدٍ، عَنْ صَالِحِ بْنِ كَيْسَانَ، عَنِ ابْنِ شِهَابٍ، قَالَ أَخْبَرَنِي مَحْمُودُ بْنُ الرَّبِيعِ، وَهُوَ الَّذِي مَجَّ رَسُولُ اللَّهِ ﷺ فِي وَجْهِهِ وَهْوَ غُلاَمٌ مِنْ بِئْرِهِمْ.
