Ali ibn Ibrahim narrated from his father, from Ibn Abi Umayr, from Hammad, from al-Halabi: Abu Abdillah عليه السلام was asked about a man who has a wound on his arm or a similar area required for wudu (ablution). The wound is bandaged with a cloth, and he performs ablution and wipes over it. Imam عليه السلام said: "If water harms him, then he should wipe over the cloth. But if water does not harm him, then he should remove the cloth and wash the wound." He (Narrator) further said: “I asked Imam عليه السلام about a cut - how should it be washed?” Imam عليه السلام said: "Wash around it."
