It is narrated from Hazrat Imran (may Allah be pleased with him) that a man came to the service of the Prophet (peace and blessings be upon him) and said, "As-Salamu Alaikum." The Prophet (peace and blessings be upon him) replied to him, and when he sat down, he said, "Ten." Another came and said, "As-Salamu Alaikum wa Rahmatullah." The Prophet (peace and blessings be upon him) also replied to him, and when he sat down, he said, "Twenty." Then a third came and said, "As-Salamu Alaikum wa Rahmatullahi wa Barakatuh." The Prophet (peace and blessings be upon him) also replied to him, and when he sat down, he said, "Thirty (good deeds)."
