28-21 Ahmad ibn Muhammad ibn Yahya al-Attar (s) - may God be pleased with him - narrated that his father quoted on the authority of Ahmad ibn Yahya ibn Imran al-Ash’ari, on the authority of Mo’awiya ibn Hakim, on the authority of Mo’ammar ibn Khallad, on the authority of Abil Hassan (s), “It is not proper for a man to smell bad on any day. If it is not possible for him to put perfume on everyday, he should at least do so every other day. Even if he cannot do so, he should try to do it once a week and not abandon this.”
