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."

that he asked Anas bin Malik: "Did the Companions of the Messenger of Allah (ﷺ) use to shake each other's hand?" He said, "Yes."

that the Prophet (ﷺ) said: "taking hold of the hand is from the completeness of the greeting."

that the Messenger of Allah (ﷺ) said: "From the complete of visiting the ill is that one of you place his hand on his forehead" - or he said - "on his hand, and ask him how he is. And shaking hands completes your greetings among each other."

"Zaid bin Harithah arrived in Al-Madinah while the Messenger of Allah (ﷺ) was in his house. So he went and knocked at the door, so the Messenger of Allah (ﷺ) stood naked (1), dragging his garment - and by Allah! I did not see him naked before nor afterwards - and he hugged him and kissed him."(1) They say that the meaning of naked here is that he was not wearing his Rida or upper wrap and it was that which was dragging, so the area between the navel and knees were covered. See Tuhfat Al-Ahwadhi.

"A Jew said to his companion: 'Accompany us to this Prophet.' So his companion said: 'Do not say: "Prophet". For if he hears you (say that) then he will be very happy.' So they went to the Messenger of Allah (ﷺ) to question him about nine clear signs. So he said to them: 'Do not associate anything with Allah, nor steal, nor commit unlawful intercourse, nor take a life which Allah has made prohibited prohibited, except for what is required (in the law), nor hasten to damage the reputation of one of power so that he will be killed, nor practice magic, nor consume Riba, nor falsely accuse the chaste woman, nor turn to flee on the day of the march, and for you Jews particularly, to not violate the Sabbath.'" He said: "So they kissed his hands and his feet, and they said: 'We bear witness that you are a Prophet.' So he (ﷺ) said: 'Then what prevents you from following me?' They said: 'Because Dawud supplicated to his Lord that his offspring never be devoid of Prophets and we feared that if we follow you then the Jews will kill us.'"

"I went to the Messenger of Allah (ﷺ) during the Year of the Conquest, and I found him performing Ghusl, while Fatimah was screening him with a garment. She said: "So I gave Salam and he said: 'Who is this?' I said: 'I am Umm Hani.' He said: 'Welcome Umm Hani'"

"The day that I came to him, the Messenger of Allah (ﷺ) said: "Welcome to the riding emigrant.'"There are narrations on this topic from Buraidah, Ibn 'Abbas, and Abu Juhaifah.
