Najiyah ‘Anazi (may Allah have mercy on him) says that there was a difference of opinion between Hazrat ‘Ammar (may Allah be pleased with him) and ‘Abdullah bin Mas‘ud (may Allah be pleased with him) regarding the issue of tayammum for a person in a state of janabah. Hazrat ‘Abdullah bin Mas‘ud (may Allah be pleased with him) said:“If I do not find water for a month after becoming junub, even then I will not pray without performing ghusl.”Hazrat ‘Ammar (may Allah be pleased with him) said:“Do you not remember that incident when once you and I were in a camel enclosure, and during the night I became junub, so I rolled in the dust like an animal, and when we returned to the service of the Prophet (peace and blessings be upon him), I mentioned this to the Prophet (peace and blessings be upon him), and the Prophet (peace and blessings be upon him) said: ‘For you, tayammum would have been sufficient.’”
