Chapter: Returning (the greeting of) peace
It was narrated from Abu Hurairah that: a man entered the masjid, and the Messenger of Allah(ﷺ) was sitting in a corner of the mosque. He prayed, then he came and greeted him with Salam(peace), and he said: 'Wa 'alaikassalm.
It was narrated from Abu Salamah that 'Aishah told him that the Messenger of Allah(ﷺ) said to her: Jibrail send (greetings of) Salam to you. She said: Wa 'alahisalam wa rahmatullah (and upon him be peace and mercy of Allah).
