Sunan Ibn Majah, Volume 3, Book 9, Hadith 1943 (DarusSalam) ⓘ

It was narrated that 'Aishah said: “Sahlah bint Suhail came to the Prophet and said: 'O Messenger of Allah, I see signs of displeasure on the face of Abu Hudhaifah when Salim enters upon me.” The Prophet said: “Breastfeed him.” She said: “How can I breastfeed him when he is a grown man? The Messenger of Allah smiled and said: “I know that he is a grown man.” So she did that, then she came to the Prophet and said: “I have never seen any signs of displeasure on the face of Abu Hudhayfah after that.” And he was present at (the battle of) Badr.

حَدَّثَنَا هِشَامُ بْنُ عَمَّارٍ، حَدَّثَنَا سُفْيَانُ بْنُ عُيَيْنَةَ، عَنْ عَبْدِ الرَّحْمَنِ بْنِ الْقَاسِمِ، عَنْ أَبِيهِ، عَنْ عَائِشَةَ، قَالَتْ جَاءَتْ سَهْلَةُ بِنْتُ سُهَيْلٍ إِلَى النَّبِيِّ ـ صلى الله عليه وسلم ـ فَقَالَتْ يَا رَسُولَ اللَّهِ إِنِّي أَرَى فِي وَجْهِ أَبِي حُذَيْفَةَ الْكَرَاهِيَةَ مِنْ دُخُولِ سَالِمٍ عَلَىَّ ‏.‏ فَقَالَ النَّبِيُّ ـ صلى الله عليه وسلم ـ ‏"‏ أَرْضِعِيهِ ‏"‏ ‏.‏ قَالَتْ كَيْفَ أُرْضِعُهُ وَهُوَ رَجُلٌ كَبِيرٌ فَتَبَسَّمَ رَسُولُ اللَّهِ ـ صلى الله عليه وسلم ـ وَقَالَ ‏"‏ قَدْ عَلِمْتُ أَنَّهُ رَجُلٌ كَبِيرٌ ‏"‏ ‏.‏ فَفَعَلَتْ فَأَتَتِ النَّبِيَّ ـ صلى الله عليه وسلم ـ فَقَالَتْ مَا رَأَيْتُ فِي وَجْهِ أَبِي حُذَيْفَةَ شَيْئًا أَكْرَهُهُ بَعْدُ ‏.‏ وَكَانَ شَهِدَ بَدْرًا ‏.‏
