[Machine] The Messenger of Allah (peace and blessings be upon him) forbade the trimming of horse's tails, their feathers, and their forelocks. He said, "Their tails are their fly whisks, their feathers are their armor, and their forelocks are tied with blessings until the Day of Judgment."  

نَهَى رَسُولُ اللهِ ﷺ عَنْ نَتْفِ أَذْنَابِ الْخَيْلِ وَأَعْرَافِهَا وَنَوَاصِيهَا وَقَالَ أَذْنَابُهَا مَذَابُّهَا وَأَعْرَافُهَا إِدْفَاؤُهَا وَنَوَاصِيهَا مَعْقُودٌ بِهَا الْخَيْرُ إِلَى يَوْمِ الْقِيَامَةِ  

[Machine] The Prophet ﷺ forbade cutting off the tails of horses, as well as their manes and forelocks. As for the tails, they are their beautification, and as for the forelocks, they are their protection, and as for the manes, goodness is intertwined in them.  

أَنَّ النَّبِيَّ ﷺ «نَهَى عَنْ جَزِّ أَذْنَابِ الْخَيْلِ وَنَوَاصِيِهَا وأَعْرافِها فَأَمَّا أَذْنَابُهَا فَإِنَّهَا مَذَابُّهَا وَأَمَّا أَعْرَافُهَا فَإِنَّهَا إِدْفَاؤُهَا وَأَمَّا نَوَاصِيهَا فَإِنَّ الْخَيْرَ مَعْقُودٌ فِيهَا»  

" نَهَى رَسُولُ الله ﷺ عَنْ جَزّ ذِنَابِ الخَيلِ وَأعْرَافِهَا وَنَواصِيهَا، وَقَالَ: أَمَّا أَعرَافُهَا فَإِنَّها أَدْفَاؤُهَا، وَأَمَّا أَذْنَابُهُا فَإِنَّهَا مَذَابُهَا، وَأَمَّا نَوَاصِيهَا فَإنَّ الْخَيْر مَعْقُودُ فِى نَواصِيهَا".
