20. Muhammad ibn Yahya has narrated from Ahmad ibn Muhammad from Ahmad ibn al-Hassan ibn Ali from ‘Amr ibn Sa‘id from Musaddiq ibn Sadaqah from ‘Ammar ibn Musa who has said the following: “I once asked abu ‘Abd Allah عليه السلام, about a man who wears a comforter with one side red and the other side yellow which is one or two years old. He (the Imam) said, ‘It is not harmful as long as it does not smell, and every cloth which is dyed and washed is useable unless it is not washed in which case it is not useable.’”
