tirmidhi:2798al-Ḥasan b. ʿAlī al-Khalāal > ʿAbd al-Razzāq > Maʿmar > Abū al-Zinād > Ibn Jarhad from his father

"Ibn Jarhad informed me from his father, that the Prophet ﷺ passed by him while his thigh was exposed, so the Prophet ﷺ said: 'Cover your thigh, for indeed it is 'Awrah.'"  

Abū ʿĪsá said that this Ḥadīth is Ḥasan.
الترمذي:٢٧٩٨حَدَّثَنَا الْحَسَنُ بْنُ عَلِيٍّ الْخَلاَّلُ حَدَّثَنَا عَبْدُ الرَّزَّاقِ أَخْبَرَنَا مَعْمَرٌ عَنْ أَبِي الزِّنَادِ أَخْبَرَنِي ابْنُ جَرْهَدٍ عَنْ أَبِيهِ

أَنَّ النَّبِيَّ ﷺ مَرَّ بِهِ وَهُوَ كَاشِفٌ عَنْ فَخِذِهِ فَقَالَ النَّبِيُّ ﷺ غَطِّ فَخِذَكَ فَإِنَّهَا مِنَ الْعَوْرَةِ  

قَالَ أَبُو عِيسَى هَذَا حَدِيثٌ حَسَنٌ
