15. Ishaq has said that narrated to me Ali ibn Zayd ibn Ali ibn al-Husayn ibn Ali عليه السلام the following. “I had a horse that I liked very much and I would admire it often in gatherings. One day I went to see abu Muhammad عليه السلام and he said, “What has your horse done?” I said, “I still have it and it is in front of your. I just dismounted it.” He said, “Change it before this evening if you can if you would find a buyer and do not delay.” Someone came in and our conversation discontinued. I then left anxiously for home and informed my brother about it and he said, “I do not know what to say about it.” I felt covetous about it procrastinated in offering for sale until it was evening we had just prayed the late evening prayer that the horse trainer came in saying, “My master your horse has died.” I became sad and realized that this was abu Muhammad عليه السلام meant. After several day I went to see abu Muhammad عليه السلام and I was saying to myself, “I wish he would replace my horse with another one. It was his words that made me so sad.” When I sat down he said, “Yes, we will replace your horse. Young man, give to him my dark brown nag which better than your horse to ride and will live longer.”
