Arabic hadith text
وَحَدَّثَنِي عَنْ مَالِكٍ، عَنْ أَيُّوبَ بْنِ مُوسَى، أَنَّ عَبْدَ اللَّهِ بْنَ عُمَرَ، نَظَرَ فِي الْمِرْآةِ لِشَكْوٍ كَانَ بِعَيْنَيْهِ وَهُوَ مُحْرِمٌ ‏.‏
Translation

Yahya related to me from Malik from Ayyub ibn Musa that Abdullahibn Umar once looked in the mirror for something that was irritatinghim while he was in ihram.
