Hadith 503680
Chapter 9: Shortening the Prayer - كتاب قصر الصلاة فى السفر
وَحَدَّثَنِي عَنْ مَالِكٍ، أَنَّهُ بَلَغَهُ أَنَّ عَبْدَ اللَّهِ بْنَ عُمَرَ، كَانَ يَكْرَهُ أَنْ يَمُرَّ، بَيْنَ أَيْدِي النِّسَاءِ وَهُنَّ يُصَلِّينَ .
Yahya related to me from Malik that he had heard that Abdullah ibn Umar used to disapprove of passing in front of women while they were praying.
