Shaqiq (may Allah have mercy on him) narrates that I was present in the company of Sayyiduna Abdullah bin Mas'ud (may Allah be pleased with him) and Sayyiduna Abu Musa Ash'ari (may Allah be pleased with him). Sayyiduna Abu Musa said to Sayyiduna Abdullah bin Mas'ud (may Allah be pleased with him): "If a person is in need of ghusl and does not find water for a whole month, should he not perform tayammum and pray?" Shaqiq says that Sayyiduna Abdullah bin Mas'ud replied: "He should not perform tayammum, even if he does not find water for a month (and should suspend the prayer)." Upon this, Abu Musa said: "Then what is the meaning of this verse in Surah Al-Ma'idah: 'If you do not find water, then perform tayammum with clean earth'?" Sayyiduna Abdullah bin Mas'ud (may Allah be pleased with him) said: "If people are given this permission, then soon it will happen that whenever they find the water cold, they will perform tayammum with earth." The narrator states: "I said, so you dislike tayammum for a person in the state of janabah?" He said: "Yes." Then Sayyiduna Abu Musa said: "Do you not know the statement of Sayyiduna Ammar (may Allah be pleased with him) before Sayyiduna Umar bin Khattab (may Allah be pleased with him): 'The Messenger of Allah (peace and blessings be upon him) sent me for a task, and during the journey I needed to perform ghusl but did not find water, so I rolled in the earth like an animal. Then I mentioned this to the Messenger of Allah (peace and blessings be upon him), and he said: 'It would have been sufficient for you to do this,' and he struck his hands on the earth once, then shook them off, then wiped the back of his right hand with his left or wiped his left hand with his right, then wiped his face with both hands.'" Sayyiduna Abdullah (may Allah be pleased with him) replied: "Do you not see that Sayyiduna Umar (may Allah be pleased with him) was not satisfied with Ammar's statement?"
