It has been narrated on the authority of Abn Huraira that the Messenger of Allah ﷺ used to dislike the Shikal horse.

كَانَ رَسُولُ اللَّهِ ﷺ يَكْرَهُ الشِّكَالَ مِنَ الْخَيْلِ

This tradition has been narrated on the authority of Sufyan with the addition from Abd ar-Razzaq (one of the narrators) explaining the meaning of shikal as a bone whose right back foot and left front foot or left back foot and right front foot are white.

عَنْ سُفْيَانَ بِهَذَا الإِسْنَادِ مِثْلَهُ وَزَادَ فِي حَدِيثِ عَبْدِ الرَّزَّاقِ وَالشِّكَالُ أَنْ يَكُونَ الْفَرَسُ فِي رِجْلِهِ الْيُمْنَى بَيَاضٌ وَفِي يَدِهِ الْيُسْرَى أَوْ فِي يَدِهِ الْيُمْنَى وَرِجْلِهِ الْيُسْرَى

The tradition has been handed down through a different chain of transmitters.

عَنِ النَّبِيِّ ﷺ بِمِثْلِ حَدِيثِ وَكِيعٍ وَفِي رِوَايَةِ وَهْبٍ عَنْ عَبْدِ اللَّهِ بْنِ يَزِيدَ وَلَمْ يَذْكُرِ النَّخَعِيَّ
