حَدَّثَنَا مُحَمَّدُ بْنُ سَابِقٍ حَدَّثَنَا إِسْرَائِيلُ عَنْ أَبِي يَحْيَى الْقَتَّاتِ عَنْ مُجَاهِدٍ عَنِ ابْنِ عَبَّاسٍ قَالَ مَرَّ رَسُولُ اللَّهِ صَلَّى اللَّهُ عَلَيْهِ وَسَلَّمَ عَلَى رَجُلٍ وَفَخِذُهُ خَارِجَةٌ فَقَالَ غَطِّ فَخِذَكَ فَإِنَّ فَخِذَ الرَّجُلِ مِنْ عَوْرَتِهِ
مسند امام احمد بن حنبل · Hadith 2493
It was narrated that Ibn 'Abbas (RA) said: The Messenger of Allah (PBUH) passed by a man whose thigh was showing. He said: "Cover your thigh, for a man's thigh is part of his 'awrah."
