356 - Ahmad ibn al-Azhar narrated to us, saying: Abu al-Abbas al-Dimashqi narrated to us, from al-Awza'i; he said: He was asked about the person suffering from smallpox (al-majdur), should he perform tayammum with the earth? He said: "Yes, if he fears for his life."
And he was asked about the sick person also performing tayammum? He said: "The sick person who has no one with him to hand him water, and is unable to stand... (1)"
In a case of extreme cold, he asked for a legal opinion, and he was told to perform ghusl (full body wash). He became rigid and died. This reached the Prophet, peace and blessings be upon him, and he said: "They killed him, may Allah kill them! The cure for ignorance is the question."
Chapter: Tayammum while present (in the city/not traveling)
• I said to Ishaq ibn Ibrahim: What about a man from the city who is a farsakh away, and he is not on a journey, and the time for prayer arrives, and he does not have water; should he perform tayammum and pray? He said: "Yes, he should perform tayammum and pray." I said: And should he repeat it? He said: "No, and I hold the opinion that tayammum is permissible while present (in the city)."
