(a) Hisham bin Hassan (may Allah have mercy on him) said: A man came to al-Hasan (may Allah have mercy on him) and asked him while I was listening. He said: His thigh or his shin was broken and he became junub (what should he do?). He ordered him to wipe over the splints.
(b) Imran bin Hudayr (may Allah have mercy on him) said: I had a severe sore from the plague and I became junub, so I asked Abu Mijlaz (may Allah have mercy on him), and he said: Wipe, for that is sufficient for you.
