Abu Abdur Rahman Salami narrates that when Sayyiduna Uthman Ghani (may Allah be pleased with him) was besieged, he looked towards the people and said: "I ask you by the name of Allah, and I give this oath only to the companions of the Prophet (peace and blessings be upon him), do you not know that the Prophet (peace and blessings be upon him) said: 'Whoever digs the well of Rumah (i.e., dedicates it as a waqf), he will be granted Paradise.' So I had it dug." Do you not know that the Prophet (peace and blessings be upon him) said: 'Whoever equips the army of Tabuk, he will be granted Paradise.' I had equipped it." So the people confirmed this statement of Sayyiduna Uthman (may Allah be pleased with him). Then Sayyiduna Uthman Ghani (may Allah be pleased with him) said that the Prophet (peace and blessings be upon him) said: "Whoever equips the army of Tabuk."
