Yahya related to me from Malik from Hisham ibn Urwa from his father that Asma bint Abi Bakr had worn clothes that were completely dyed with safflower while she was in ihram, though there was not any saffron in them.
Yahya said that Malik was asked if a garment which had been perfumed could be used for ihram if the smell of the perfume had gone, and he said, "Yes, as long as there is no saffron or yellow dye in it."

وَحَدَّثَنِي عَنْ مَالِكٍ، عَنْ هِشَامِ بْنِ عُرْوَةَ، عَنْ أَبِيهِ، عَنْ أَسْمَاءَ بِنْتِ أَبِي بَكْرٍ، أَنَّهَا كَانَتْ تَلْبَسُ الثِّيَابَ الْمُعَصْفَرَاتِ الْمُشَبَّعَاتِ وَهِيَ مُحْرِمَةٌ لَيْسَ فِيهَا زَعْفَرَانٌ . قَالَ يَحْيَى سُئِلَ مَالِكٌ عَنْ ثَوْبٍ مَسَّهُ طِيبٌ ثُمَّ ذَهَبَ مِنْهُ رِيحُ الطِّيبِ هَلْ يُحْرِمُ فِيهِ فَقَالَ نَعَمْ مَا لَمْ يَكُنْ فِيهِ صِبَاغٌ زَعْفَرَانٌ أَوْ وَرْسٌ .
