Chapter 147 | The Case of One Who Forgets Taqsir until Talbiyah (Here I Am, O Lord, to obey Your command) for al-Hajj or Shaves His Head or Has Carnal Relations with His Wife
8ـ عَلِيُّ بْنُ إِبْرَاهِيمَ عَنْ أَبِيهِ عَنِ ابْنِ أَبِي عُمَيْرٍ عَنْ حَفْصِ بْنِ الْبَخْتَرِيِّ عَنْ غَيْرِ وَاحِدٍ عَنْ أَبِي عَبْدِ الله (عَلَيْهِ السَّلاَم) قَالَ يَنْبَغِي لِلْمُتَمَتِّعِ بِالْعُمْرَةِ إِلَى الْحَجِّ إِذَا أَحَلَّ أَنْ لا يَلْبَسَ قَمِيصاً وَلْيَتَشَبَّهْ بِالْمُحْرِمِينَ.
8. Ali ibn Ibrahim has narrated from his father from Ibn Abi ‘Umayr from Hafs ibn al-Bakhtariy from more than one person who has said the following: “Abu ‘Abd Allah , has said, ‘It is very proper for one who is for al-Hajj al-Tamattu‘ (advantageous), that after coming out of the state of Ihram, he should not dress up with a shirt to remain like those in the state of Ihram.’”
