وَ سُئِلَ اَلصَّادِقُ عَلَيْهِ اَلسَّلاَمُ: عَنِ اَلْمُحْرِمِ يَشَمُّ اَلرَّيْحَانَ قَالَ «لاَ» قِيلَ فَالصَّائِمُ قَالَ «لاَ» قِيلَ يَشَمُّ اَلصَّائِمُ اَلْغَالِيَةَ وَ اَلدُّخْنَةَ قَالَ «نَعَمْ» قِيلَ كَيْفَ حَلَّ لَهُ أَنْ يَشَمَّ اَلطِّيبَ وَ لاَ يَشَمَّ اَلرَّيْحَانَ قَالَ «لِأَنَّ اَلطِّيبَ سُنَّةٌ وَ اَلرَّيْحَانَ بِدْعَةٌ لِلصَّائِمِ ».
Imam Jafar ibn Muhammad Al-Sadiq (a.s) was asked about a person in a state of Ihram smelling basil. Imam (a.s) said: "No." Imam (a.s) was asked about a fasting person. Imam (a.s) said: "No." Imam (a.s) was asked if a fasting person may smell perfume or incense. Imam (a.s) said: "Yes." Imam (a.s) was asked: "How is it permissible for him to smell perfume but not basil?" Imam (a.s) replied: "Because perfume is a Sunnah, while basil is an innovation for the fasting person."
