Regarding greeting children
Sunan Abi Dawud
حَدَّثَنَا عَبْدُ اللَّهِ بْنُ مَسْلَمَةَ، حَدَّثَنَا سُلَيْمَانُ، - يَعْنِي ابْنَ الْمُغِيرَةِ - عَنْ ثَابِتٍ، قَالَ قَالَ أَنَسٌ أَتَى رَسُولُ اللَّهِ صلى الله عليه وسلم عَلَى غِلْمَانٍ يَلْعَبُونَ فَسَلَّمَ عَلَيْهِمْ .
Narrated Anas ibn Malik: The Messenger of Allah (ﷺ) came to some children who were playing: He saluted them.
