Sahih Muslim , Book 24, Hadith 5285 (USC-MSA) ⓘ

Anas reported that Umm Sulaim gave birth to a child. She said to him: Anas, see that nothing is given to this child until he is brought to Allah's Apostle in the morning, so that he should chew some dates and touch his palate with it. I went to him in the morning and he was in the garden at that time having the mantle of Jauniyya over him and he was bus in cauterising (the camels) which had been brought to him (as spoils of war) in victory (over the enemy).

حَدَّثَنَا مُحَمَّدُ بْنُ الْمُثَنَّى، حَدَّثَنِي مُحَمَّدُ بْنُ أَبِي عَدِيٍّ، عَنِ ابْنِ عَوْنٍ، عَنْ مُحَمَّدٍ، عَنْ أَنَسٍ، قَالَ لَمَّا وَلَدَتْ أُمُّ سُلَيْمٍ قَالَتْ لِي يَا أَنَسُ انْظُرْ هَذَا الْغُلاَمَ فَلاَ يُصِيبَنَّ شَيْئًا حَتَّى تَغْدُوَ بِهِ إِلَى النَّبِيِّ صلى الله عليه وسلم يُحَنِّكُهُ ‏.‏ قَالَ فَغَدَوْتُ فَإِذَا هُوَ فِي الْحَائِطِ وَعَلَيْهِ خَمِيصَةٌ جَوْنِيَّةٌ وَهُوَ يَسِمُ الظَّهْرَ الَّذِي قَدِمَ عَلَيْهِ فِي الْفَتْحِ ‏.‏
