We set out with the Prophet ﷺ in the year of Al-Hudaibiya, and all his companions assumed the state of Ihram but I did not.  

البخاري:٤١٤٩حَدَّثَنَا سَعِيدُ بْنُ الرَّبِيعِ حَدَّثَنَا عَلِيُّ بْنُ الْمُبَارَكِ عَنْ يَحْيَى عَنْ عَبْدِ اللَّهِ بْنِ أَبِي قَتَادَةَ أَنَّ أَبَاهُ حَدَّثَهُ

قَالَ انْطَلَقْنَا مَعَ النَّبِيِّ ﷺ عَامَ الْحُدَيْبِيَةِ فَأَحْرَمَ أَصْحَابُهُ وَلَمْ أُحْرِمْ
