What do you want to know about the greeting of Islam?

The greeting of Islam is the greeting of Adam and his offspring. Allah Almighty commanded Adam to go and greet the angels, so he greeted them by saying: "Peace be upon you (As-salamu alaykum)." They replied to him: "Peace be upon you and the mercy of Allah (As-salamu alayka wa rahmatullah)." This became his greeting and the greeting of his offspring. It is superior to the greeting of the pre-Islamic era of ignorance, "May your morning be pleasant," and Allah has replaced it for Muslims with the greeting of the people of Paradise, which is "Peace (As-Salam)."
