'I was in the presence of Abu Abdillah [al-Sadiq] (AS), when a man said to him, may Allah make you well, you mentioned that 'Ali b. Abi Talib (AS) would wear rough clothes and would wear a shirt that was worth four dirhams, and things similar to that, but we see you are wearing good clothes!' (He said], 'The Imam replied to him, Ali b. Abi Talib (AS) wore that in a time in which it would not be disapproved, and if he would wear those clothes today he would be defamed for it. Therefore, the best clothing of every time is the clothing of the people [of that time]. However, when our al-Qa?im [the awaited saviour Imam al-Mahdi, may Allah hasten his appearance] reappears he will be wearing the clothes of ?Ali (AS) and will follow his way of life.'
