٧ـ مُحَمَّدُ بْنُ يَحْيَى عَنْ أَحْمَدَ بْنِ مُحَمَّدٍ عَنْ إِبْرَاهِيمَ بْنِ أَبِي مَحْمُودٍ قَالَ قُلْتُ لِلرِّضَا (عَلَيْهِ الْسَّلام) الرَّجُلُ يُجْنِبُ فَيُصِيبُ جَسَدَهُ وَرَأْسَهُ الْخَلُوقُ وَالطِّيبُ وَالشَّيْ‏ءُ اللَّكِدُ مِثْلُ عِلْكِ الرُّومِ وَالطَّرَارِ وَمَا أَشْبَهَهُ فَيَغْتَسِلُ فَإِذَا فَرَغَ وَجَدَ شَيْئاً قَدْ بَقِيَ فِي جَسَدِهِ مِنْ أَثَرِ الْخَلُوقِ وَالطِّيبِ وَغَيْرِهِ قَالَ لاَ بَأْسَ.
7. Muhammad ibn Yahya has narrated from Ahmad ibn Muhammad from Ibrahim ibn abu Mahmud who has said the following: “I once asked al-Rida , ‘Is it permissible for one after experiencing sexual relation to come in contact with perfume, oils or such things as chewing-gum or freshener, then take Ghusl (bath)? What happens if such one afterwards finds pieces left on one’s body or marks of rubbing oil or perfumes and so on?’ He (the Imam) said, ‘It is not harmful.’”
