Anas ibn Malik · Chapters on Seeking Permission

that the Prophet (ﷺ) passed by a gathering in which the Muslims and the Jews were mixed, so he gave the Salam to them.

that the Messenger of Allah (ﷺ) said: "No two Muslims meet each other and shake hands, except that Allah forgives them before they part."

that a man said: "O Messenger of Allah! When a man among us meets his brother or his friend should he bow to him?" He said: "No." The man continued: "Should he embrace him and kiss him?" He said: "No." He said: "Should he take his hand and shake it?" He said: "Yes."
