مُحَمَّدُ بْنُ يَحْيَى عَنْ أَحْمَدَ بْنِ مُحَمَّدٍ عَنْ مُعَمَّرِ بْنِ خَلَّادٍ عَنْ أَبِي الْحَسَنِ ( عليه السلام ) قَالَ لَا يَنْبَغِي لِلرَّجُلِ أَنْ يَدَعَ الطِّيبَ فِي كُلِّ يَوْمٍ فَإِنْ لَمْ يَقْدِرْ عَلَيْهِ فَيَوْمٌ وَ يَوْمٌ لَا فَإِنْ لَمْ يَقْدِرْ فَفِي كُلِّ جُمُعَةٍ وَ لَا يَدَعْ .

4. Muhammad ibn Yahya has narrated from Ahmad ibn Muhammad from Mu’ammar ibn Khallad who has said the following: “Abu al-Hassan, ‘Alayhi al-Salam, has said, ‘A man must not ignore using perfumes every day, or every other day, if he cannot afford. If he cannot afford this, he must use perfume every Friday.’”
