الحسن بن علوان عن سعد بن طريف عن زيد بن علي عن آبائه عن علي عليه السلام قال: إن في الجنة لشجرة يخرج من أعلاها الحلل ومن أسفلها خيل بلق مسرجة ملجمة ذوات أجنحة لا تروث ولا تبول (فيركبها) فيركب عليها أولياء الله فتطير بهم في الجنة حيث شاؤوا فيقول الذين أسفل منهم: يا ربنا ما بلغ بعبادك هذه الكرامة؟ فيقول الله جل جلاله: انهم كانوا يقومون الليل ولا ينامون ويصومون النهار ولا يأكلون ويجاهدون العدو ولا يجنبون ويتصدقون ولا يبخلون
7.Al-Ḥasan ibn ʿUlwān narrated from Saʿd ibn Ṭarīf, from Zayd ibn ʿAlī, from his fathers, from ʿAlī  who said, “Verily there is a tree in Paradise from the top of which [paradisal] garments come forth, and from the bottom of which come horses of mixed black and white colour, saddled, bridled, and with  wings, that neither defecate or urinate. They are mounted by the friends of Allah who fly with them wherever they wish in Paradise, so those who are below them will say, ‘Our Lord, what made these servants of Yours reach such a noble station?’ So Allah, the Mighty and Majestic, will say, ‘They would stand up [to worship] in the night and would not sleep, they would fast during the day and not eat, they would fight the enemy and were not cowardly, and they would give charity and were not miserly.’”
