Another one came and said: "As-Salamu 'Alaikum wa Rahmatullah (May peace be upon you and the Mercy of Allah)." The Messenger of Allah (ﷺ) responded to his greeting and the man sat down. The Messenger of Allah (ﷺ) said, "Twenty." A third one came and said: "As-Salamu 'Alaikum wa Rahmatullahi wa Barakatuhu (May peace be upon you and the Mercy of Allah and His Blessings)."
