Muwatta Imam Malik Book of Hajj, Hadith 15
Yahya related to me from Malik from Nafi that Abdullah ibn Umar used to say that a woman in ihram should wear neither a veil nor gloves.
وَحَدَّثَنِي عَنْ مَالِكٍ، عَنْ نَافِعٍ، أَنَّ عَبْدَ اللَّهِ بْنَ عُمَرَ، كَانَ يَقُولُ لاَ تَنْتَقِبُ الْمَرْأَةُ الْمُحْرِمَةُ وَلاَ تَلْبَسُ الْقُفَّازَيْنِ .
