The Book of Asceticism · Hadith 120 (#Ḥadīth #3)

فضالة عن أبان بن عثمان عن زياد بن أبي رجاء عن أبي عبد الله عليه السلام وعن أبي سخل عن سلمان قال: بينا انا جالس عند رسول الله صلى الله عليه وآله إذا قصد له رجل فقال يا رسول الله: المملوك فقال رسول الله صلى الله عليه وآله ابتلى بك وبليت به لينظر الله عز وجل كيف تشكر وينظر كيف يصبر.

3.Faḍālah narrated from Abān ibn ʿUthmān, from Ziyād ibn Abī Rajāʾ, from Abū ʿAbdillāh ; and from Abū Sakhl, from Salmān who said, “I was once sitting in the presence of the Messenger of Allah (ṣ) when a man came to him and said, ‘O Messenger of Allah, [what do you say about] the slave?’ So the Messenger of Allah (ṣ) said, ‘He has been tested by you and you have been tested by him, so that Allah, the Mighty and Majestic, may see how grateful you are and how patient he is.’”
