The Book of Asceticism · Hadith 126 (#Ḥadīth #4)

عثمان بن عيسى عن سماعة قال: سمعت أبا عبد الله عليه السلام يقول: اصبروا على طاعة الله واصبروا من معاصي الله فإنما الدنيا ساعة فما مضى منها فلست تعرفه فاصبر على تلك الساعة التي أنت فيها وكانت قد أعطيت.

4.ʿUthmān ibn ʿĪsā narrated from Samāʿah who said, “I heard Abā ʿAbdillāh say, ‘Remain patient in obeying Allah, and remain patient in keeping away from disobeying Allah, for indeed this world is short lived; that which has passed from it is [such that you find neither joy nor sorrow for it now, while that which has not yet come is] [1] unknown to you, so remain patient in the present moment that you are in, and it will be as though you have been granted [its reward].’”
