Ali ibn al-Husayn narrated from Muhammad ibn Ahmad ibn Ali, from Abdullah ibn al-Salt, from Ibn Abi Umayr, from Hammad, from al-Halabi, from Abu Abdullah عليه السلام: Imam عليه السلام was asked about a man washing his wife. Imam عليه السلام said: "Yes, he may wash her from behind the garment, without looking at her hair or any part of her body. A woman may also wash her husband because, if he dies, she remains in his waiting period (iddah). However, if she dies, her waiting period is already completed." Imam عليه السلام was also asked about a woman who dies while traveling, and there is no Mahram (male guardian) or other women with her. Imam عليه السلام said: "She should be buried as she is, in her clothes." Imam عليه السلام was further asked about a man who dies while traveling, and there is no Mahram or other men with him. Imam عليه السلام said: "He should be buried as he is, in his clothes."
