Hadith.4225 - And in the narration of Abdullah ibn al-Mughirah from Burd, he said: I said to Abu Abdullah (as): 'May I be your ransom! We work with pig hair, and sometimes a man forgets and prays while having something of it in his hand.' Imam (as) said: 'It is not proper for him to pray while having something of it in his hand.' And Imam (as) also said: 'Take it and wash it. If it has grease, do not use it. But if it does not have grease, then you may use it, and wash your hands after handling it.'"
