«الْخَيْلُ لِثَلَاثَةٍ، لِرَجُلٍ أَجْرٌ، وَلِرَجُلٍ سِتْرٌ، وَعَلَى رَجُلٍ وِزْرٌ، فَأَمَّا الَّذِي لَهُ أَجْرٌ، فَرَجُلٌ رَبَطَهَا فِي سَبِيلِ اللهِ فَأَطَالَ لَهَا فِي مَرْجٍ أَوْ رَوْضَةٍ، فَمَا أَصَابَتْ فِي طِيَلِهَا ذَلِكَ مِنَ الْمَرْجِ أَوِ الرَّوْضَةِ، كَانَتْ لَهُ حَسَنَاتٍ وَلَوْ أَنَّهَا قَطَعَتْ طِيَلَهَا، فَاسْتَنَّتْ شَرَفًا أَوْ شَرَفَيْنِ كَانَتْ آثَارُهَا وَأرْوَاثُهَا حَسَنَاتٍ لَهُ، وَلَوْ أَنَّهَا مَرَّتْ بِنَهَرٍ فَشَرِبَتْ مِنْهُ وَلَمْ يُرِدْ أَنْ يَسْقِيَ بِهِ، كَانَ ذَلِكَ حَسَنَاتٍ لَهُ،فَهِيَ لِذَلِكَ الرَّجُلِ أَجْرٌ، وَرَجُلٌ رَبَطَهَا تَغَنِّيًا وَتَعَفُّفًا، وَلَمْ يَنْسَ حَقَّ اللهِ فِي رِقَابِهَا وَلَا ظُهُورِهَا فَهِيَ لَهُ سِتْرٌ، وَرَجُلٌ رَبَطَهَا فَخْرًا وَرِيَاءً وَنِوَاءً، فَهِيَ عَلَى ذَلِكَ وِزْر»
(Horses are kept for one of three purposes; for some people they are a source of reward, for some others they are a means of shelter, and for some others they are a source of sin. The one for whom they are a source of reward, is he who keeps a horse for Allah's cause (Jihad) tying it with a long tether on a meadow or in a garden. The result is that whatever it eats from the area of the meadow or the garden where it is tied, will be counted as good deeds for his benefit; and if it should break its rope and jump over one or two hillocks then all its dung and its footmarks will be written as good deeds for him. If it passes by a river and drinks water from it, even though he had no intention of watering it, then he will get the reward for its drinking. Therefore, this type of horse is a source of good deeds for him. As for the man who tied his horse maintaining self - sufficiency and abstinence from begging, all the while not forgetting Allah's right concerning the neck and back of his horse, then it is a means of shelter for him. And a man who tied a horse for the sake of pride, pretense and showing enmity for Muslims, then this type of horse is a source of sins.) When Allah's Messenger was asked about donkeys, he replied,
