2ـ عَلِيُّ بْنُ إِبْرَاهِيمَ عَنْ أَبِيهِ عَنْ حَمَّادٍ عَنْ حَرِيزٍ عَنْ مُحَمَّدِ بْنِ مُسْلِمٍ عَنْ أَحَدِهِمَا (عَلَيْهِما السَّلاَم) قَالَ سَأَلْتُهُ عَنْ ضُرُوبٍ مِنَ الثِّيَابِ مُخْتَلِفَةٍ يَلْبَسُهَا الْمُحْرِمُ إِذَا احْتَاجَ مَا عَلَيْهِ قَالَ لِكُلِّ صِنْفٍ مِنْهَا فِدَاءٌ.

2. Ali ibn Ibrahim has narrated from his father from Hammad from Hariz, from Muhammad ibn Muslim who has said the following: “I once asked one of the two Imam, (abu Ja’far or abu ‘Abd Allah), ‘Alayhim al-Salam, about one’s wearing different kinds of clothes in the state of Ihram, if needed. He (the Imam) said, ‘For wearing every kind there is ransom to pay.’”
