Tayammum for Junub

 166. Shaqiq said: I was sitting with ´Abdullah and Abu Musa, when the latter asked the former, O Abu Abdur Rahman, if a man becomes Junub and does not find water for one month, how can he perform his prayer?´´ He replied, ´´He shpuld not perform Tayammum even if he would not find water for one month.´´ Abu Musa said, ´´What do you say about this Verse from Surat Al-Ma´idah: ´And you find no water then perfom Tayammum with clear earth and rub with it your faces and hands.´

(V .5:6).´´ ´Abdullah replied, ´´If this Ayah is given to people as a leave, they would have performed Tayammum even when they have cold water.´´ Abu Musa said to ´Abdullah, ´´Did you not hear the report of ´Ammar? He said: The Messenger of Allah salla alayhi wa sallam sent me for some job, and I became Junub and could not find water, so I rolled myself over the dust like an animal does, and then came to the Prophet salla alayhi wa sallam and told him of that, he said, ´It would have been sufficient for you to do with your hands.´ The Prophet salla alayhi wa sallam lightly struck the earth with his hand once then passed his left hand over his right hand  and exterior of his palms and his face.´´ So ´Abdullah said, ´´Don´t you know that ´Umar was not convinced with ´Ammar´s statement?´´
