Musnad Ahmad

It is narrated from Hazrat Nu’man (may Allah be pleased with him) that once I was sitting near the pulpit of the Prophet (peace and blessings be upon him) when a man said, “After accepting Islam, I do not care if I do any deed except that I give water to the pilgrims.” Another said, “I maintain the Sacred Mosque, so after accepting Islam, I do not care about any other deed.” And a third said, “The best of what you have mentioned is Jihad.” Hazrat Umar (may Allah be pleased with him) scolded them and said, “Do not raise your voices near the pulpit of the Prophet. It was Friday, and after the prayer, I will go to the service of the Prophet (peace and blessings be upon him) and ask him about the matter in which you are differing.” At that moment, this verse was revealed: “Do you consider the giving of water to the pilgrims and the maintenance and construction of the Sacred Mosque equal to the one who believes in Allah and the Last Day?”
