English translation
1327. It was narrated that Jâbir bin Samurah said: "I prayed with the Messenger of Allâh ﷺ and when we said the Salâm we used to gesture with our hands: 'As-salâmu 'alaykum wa rahmatullâh (Peace be upon, peace be upon you).' The Messenger of Allâh ﷺ looked at us and said: 'What is the matter with you, pointing with your hands as if they are the tails of wild horses? When any one of you says the Salâm, let him turn to his companions and not gesture with his hand.'" (Sahîh)
