Sahih al-Bukhari 346

It is related that Shaqiq ibn Salama was heard to say, "I was with 'Abdullah and Abu Musa and Abu Musa said to him, ´Abu 'Abdu'r-Rahman, what do you think someone should do if he is in janaba and cannot find any water?' 'Abdullah said, 'He should not pray until he finds water.' Abu Musa said, 'So what about 'Ammar´s statement that the Prophet, may Allah bless him and grant him peace, said to him, 'It (tayammum) would have been enough for you?' He replied, 'Don't you see that 'Umar was not happy with that?' Abu Musa said, 'All right, putting aside what 'Ammar said, what do you make of this ayat (of tayammum)?''Abdullah did not know what to say and then said, ''If we were to give them a dispensation (to do tayammum) in this instance, even if they the water they found was cold, they would probably leave it and do tayammum, ' I said to Shaqiq, "Did 'Abdullah [ibn Mas'ud] dislike doing tayammum because of this?" He said, "Yes."
