Abu 'Amr was asked: What about tayammum with pebbles and smooth stones if one does not find pure earth? He said: "There is no harm in that."

378 - Al-Walid said: I asked Malik ibn Anas about tayammum with pebbles, and he said: "Place your palms upon them, then wipe your face and your hands with them," and he said: "There is no harm in it."

379 - Al-Walid said: It was said to Sufyan al-Thawri: What about tayammum with dust on grass or the leaves of a tree? He said: "There is no harm in that."

Chapter: A man who engages in intercourse with his wife in a desert, and has no water with him

• I heard Ishaq say: "If you intend to engage in intercourse with your wife while you are in a desert and you do not have water with you, then approach your wife and perform tayammum; for the Sunnah has already passed regarding Abu Dharr and others."

380 - Ishaq narrated to us, saying: Al-Mu'tamir narrated to us, saying: I heard Layth narrate from 'Ata', from Ibn 'Abbas, that he was asked about a man who is on a journey and has his wife with him, and he has no water with him, and his sexual desire has intensified? He said: "If he wishes, he may approach his wife and perform tayammum."

• And I asked Ishaq, saying: Two men are on a journey, one of them has water and the other does not. The one who has the water is too lazy to perform wudu, so he gives the water to his companion and performs tayammum himself; what is the status of the one who gave away the water? He said: "Once he has given away the water, he is like one who has no water," and he held the view that his prayer is valid, yet he is sinful.
