Abu Hurayrah (may Allah be pleased with him) reported that the Prophet (may Allah's peace and blessings be upon him) said: "The believer, man or woman, will continue to be tested with regard to his own self, children, and property until they meet Allah, the Almighty, without any sins in their record."
عن أبي هريرة -رضي الله عنه- مرفوعًا: «ما يزَال البَلاء بِالمُؤمن والمُؤمِنة في نفسه وولده وماله حتَّى يَلقَى الله تعالى وما عليه خَطِيئَة».
شرح الحديث :
The human being in this life is liable to experience pleasant and unpleasant trials. So, whenever a person is afflicted with a trial in himself, his children, or his property, yet persevered throughout the trial, it will be a cause for the expiation of his sins and misdeeds. However, if he expresses displeasure in the face of trials, Allah will be displeased with him.
