Hazrat Ibn Abbas (may Allah be pleased with them both) says in the explanation of this verse: { وَلاَ جُنُبًا إِلاَّ عَابِرِی سَبِیلٍ } that by this is meant the traveler.

Hazrat Sulaiman bin Musa says that this refers to such travelers who do not find water.

Hazrat Umar says that a person in a state of major impurity (janabah) cannot perform tayammum, even if he does not find water for a whole month.

Hazrat Abdullah says that if you become junub during a journey, do not perform prayer until you find water, and if your ablution breaks, then perform tayammum and offer prayer.

Dhahhak says that Hazrat Abdullah had retracted his statement regarding tayammum.

Hazrat Zubaid says that once I became junub, and I did not have water. I asked Hazrat Abu Atiyyah about this, and he said, "Do not pray." I asked Hazrat Saeed bin Jubair, and he said, "Perform tayammum and offer the prayer."

Hazrat Shaqiq narrates that once I was sitting with Hazrat Abdullah and Hazrat Abu Musa. Hazrat Abu Musa said: "O Abu Abdur Rahman! What is your opinion if a person is in a state of janabah and does not find water for a month, what should he do about prayer?" Hazrat Abdullah replied that he should not perform tayammum even if he does not find water for a month. Hazrat Abu Musa said: "Then what should be done about this verse of Surah Al-Ma'idah: If you do not find water, then perform tayammum with clean earth?" Hazrat Abdullah replied: "If people are given this concession, they will start performing tayammum even out of fear of cold water."

Hazrat Ata narrates that once Hazrat Abu Dharr was at a distance of three days' journey from the Holy Prophet (peace and blessings be upon him) when he became junub (in a state of major ritual impurity). Then he reached the presence of the Prophet (peace and blessings be upon him), and the Prophet (peace and blessings be upon him), after finishing the Fajr prayer, went to relieve himself. Then he turned towards Hazrat Abu Dharr and struck his hands on the earth and wiped them over his face and palms.

Hazrat Nafi' narrates that Hazrat Ibn Umar (may Allah be pleased with them) performed tayammum at the place of Marbad al-Na'am in such a way that he struck his hands on the ground and wiped them over his face, then struck them on the ground again and wiped both hands up to the elbows.

Ayyub says that I asked Hazrat Salim about tayammum, so he struck his hands on the ground and wiped them over his face, then struck them on the ground again and wiped both hands up to the elbows.
