Sayyiduna al-Nu'man bin Bashir (may Allah be pleased with him) narrated: "I was present by the pulpit of the Messenger of Allah (peace and blessings be upon him) when a man said: 'After accepting Islam, I do not care if I do no other deed except giving water to the pilgrims.' Another said: 'After accepting Islam, I do not care if I do no other deed except building and serving the Sacred Mosque.' Yet another man said: 'Jihad in the path of Allah is more excellent than what you have said.' At this Sayyiduna Umar (may Allah be pleased with him) rebuked them and said: 'Do not raise your voices by the pulpit of the Messenger of Allah (peace and blessings be upon him)' (and it was a Friday) 'but when I have prayed the Friday prayer, I will go in and ask him (peace and blessings be upon him) about what you have differed over.' Then Allah, the Mighty and Majestic, revealed this verse: 'Have you made the giving of water to the pilgrims and the maintenance of the Sacred Mosque equal to (the deeds of) one who believes in Allah?'"
This hadith is narrated from Sayyiduna al-Nu'man (may Allah be pleased with him) only with this chain.
