Sunan Ibn Majah, 3716

Rapporté par Anas bin Malik : Chaque fois que le Prophète ﷺ rencontrait quelqu’un, il lui parlait et ne se détournait pas tant que l’autre ne partait pas le premier. Et s’il lui serrait la main, il ne retirait pas sa main tant que l’autre ne la retirait pas. On ne l’a jamais vu assis avec ses genoux devant ceux de la personne assise à côté de lui

It was narrated that Anas bin Malik said:"Whenever the Prophet(ﷺ) met a man, he would speak to him, and would not tun away until he (the other man) was the one who turned away. And if he shook hands with him, he would not withdraw his hand until he (the other man) withdrew his hand. And he was never seen sitting with his knees ahead of the knees of the one who was sitting next to him
