[Machine] While the Messenger of Allah ﷺ was sitting, he laughed and said, "Will you not ask me what I am laughing at?" They asked, "What made you laugh?" He said, "I am amazed at the affair of a believer; all of his matters are good for him. If something good befalls him, he thanks Allah, which is good for him. And if something bad befalls him, he observes patience, which is also good for him. This is not the case for any person except a believer."  

بَيْنَمَا رَسُولُ اللَّهِ ﷺ جَالِسٌ إِذْ ضَحِكَ فَقَالَ «أَلَا تَسْأَلُونِي مِمَّا أَضْحَكُ؟» فَقَالُوا مِمَّ تَضْحَكُ؟ قَالَ عَجَبًا مِنْ أَمْرِ الْمُؤْمِنِ كُلُّهُ لَهُ خَيْرٌ إِنْ أَصَابَهُ مَا يُحِبُّ حَمِدَ اللَّهَ عَلَيْهِ فَكَانَ لَهُ خَيْرٌ وَإِنْ أَصَابَهُ مَا يَكْرَهُ فَصَبَرَ كَانَ لَهُ خَيْرٌ وَلَيْسَ كُلُّ أَحَدٍ أَمْرُهُ لَهُ خَيْرٌ إِلَّا الْمُؤْمِنَ
