4. It is narrated from the narrator of the previous Hadith from al-Qasim ibn Muhammad from his grandfather, al-Hassan ibn Rashid from Ya’qub ibn Ja’far ibn Ibrahim al-Ja’fariy who has said the following: “I heard abu al-Hassan , saying, ‘If one maintains a horse of pure breed, three of his sins will be deleted every day and ten good deeds will be written in his favor. If one maintains a horse of mixed breed, two of his bad deeds will be deleted every day and seven good deeds will be written in his favor. If one maintains a mule for beauty or for his needs or use in his defense against the enemy, one of his sins will be deleted every day and six good deeds will be written in his favor.’”
