Hadith #1

1ـ مُحَمَّدُ بْنُ يَحْيَى عَنْ أَحْمَدَ بْنِ مُحَمَّدٍ عَنِ الْحُسَيْنِ بْنِ سَعِيدٍ عَنِ الْقَاسِمِ بْنِ مُحَمَّدٍ عَنْ عَلِيِّ بْنِ أَبِي حَمْزَةَ قَالَ سَأَلْتُهُ عَنِ الرَّجُلِ يَدَّهِنُ بِدُهْنٍ فِيهِ طِيبٌ وَهُوَ يُرِيدُ أَنْ يُحْرِمَ قَالَ لا تَدَّهِنْ حِينَ تُرِيدُ أَنْ تُحْرِمَ بِدُهْنٍ فِيهِ مِسْكٌ وَلا عَنْبَرٌ تَبْقَى رَائِحَتُهُ فِي رَأْسِكَ بَعْدَ مَا تُحْرِمُ وَادَّهِنْ بِمَا شِئْتَ مِنَ الدُّهْنِ حِينَ تُرِيدُ أَنْ تُحْرِمَ قَبْلَ الْغُسْلِ وَبَعْدَهُ فَإِذَا أَحْرَمْتَ فَقَدْ حَرُمَ عَلَيْكَ الدُّهْنُ حَتَّى تَحِلَّ.

1. Muhammad ibn Yahya has narrated from Ahmad ibn Muhammad from al-Husayn ibn Sa‘id from al-Qasim ibn Muhammad from Ali ibn abu Hamzah who has said the following: “I once asked him (the Imam), ‘Alayhi al-Salam, about a man who uses an oil which is sweet smelling and he wants to assume the state of Ihram. He (the Imam) said, ‘You must not use sweet smelling oil with musk or ‘amber and its smell may remain on your head after you assume the state of Ihram. You can use oil of whatever kind you like before Ghusl (bath) or thereafter, but when you assume the state of Ihram, it then becomes unlawful for you to use oil until you come out of the state of Ihram.”’
