Abu Ala Yazid bin Abdullah Shikhir reported,

One of the Banu Sulaym, whom I believe to have seen the Messenger of Allah ﷺ, reported that the Messenger of Allah ﷺ said, "Allah تبارك وتعالى tests His servant through what He has given him. Whoever is content with what Allah has allotted to him, Allah will bless it for him and expand it for him, and whoever is not content, it will not be blessed for him."

Sahih

عن أبي العلاء يزيد بن عبد الله بن الشخير قال

حدثني أحد بني سليم ولا أحسبه إلا قد رأى رسول الله ﷺ قال: قال رسول الله ﷺ: إن الله تبارك وتعالى يبتلي عبده بما أعطاه، فمن رضي بما قسم الله له، بارك الله له فيه ووسعه، ومن لم يرض لم يبارك له.
