(sic) Abu'z-Zinad said, "Kharija (ibn Zayd ibn Thabit) used to
write on the letter of Zayd when he said the salam, 'Peace be upon you,
Amir al-Mu'minin, and the mercy of Allah and His blessings and His forgiveness
and the best of His prayers."
Abu Hurayra reported that the Messenger of Allah, may Allah bless
him and grant him peace, said, "The young person greets the old person,
the person walking greets the person sitting down, and the small group
greets the large group."
Abu Qurra al-Khurasani said, "I saw Anas pass by us and he indicated
to us with his hand that he was giving the greeting., The gesture made
that clear. I saw al-Hasan using yellow dye while wearing a black turban.
Asma' said, 'The Prophet, may Allah bless him and grant him peace, waved
his hand to indicate the greeting to women."
