Hadith #2

2ـ عَلِيُّ بْنُ إِبْرَاهِيمَ عَنْ أَبِيهِ عَنِ ابْنِ أَبِي عُمَيْرٍ عَنْ حَمَّادٍ عَنِ الْحَلَبِيِّ عَنْ أَبِي عَبْدِ الله (عَلَيْهِ السَّلاَم) قَالَ لا تَدَّهِنْ حِينَ تُرِيدُ أَنْ تُحْرِمَ بِدُهْنٍ فِيهِ مِسْكٌ وَلا عَنْبَرٌ مِنْ أَجْلِ رَائِحَةٍ تَبْقَى فِي رَأْسِكَ بَعْدَ مَا تُحْرِمُ وَادَّهِنْ بِمَا شِئْتَ مِنَ الدُّهْنِ حِينَ تُرِيدُ أَنْ تُحْرِمَ فَإِذَا أَحْرَمْتَ فَقَدْ حَرُمَ عَلَيْكَ الدُّهْنُ حَتَّى تَحِلَّ.

2. Ali ibn Ibrahim has narrated from his father from ibn abu ‘Umayr from Hammad from al-Halabiy who has said the following: “Abu ‘Abd Allah, ‘Alayhi al-Salam, has said, ‘You must not apply any oil which has musk or ambergris; for its perfume remains in your head after Ihram. You can apply oil when you want to assume the state of Ihram, once you are in the state of Ihram; applying becomes unlawful until you come out of the state of Ihram.’”
