Messenger of Allah ﷺ said, "If Allah wants to do good to somebody, He afflicts him with trials."  

قَالَ رَسُولُ اللَّهِ ﷺ: «مَنْ يُرِدِ اللَّهُ بِهِ خَيْرًا يُصِبْ مِنْهُ۔»  

The Prophet ﷺ said, "Soon others will be preferred to you, and there will be things which you will not like." The companions of the Prophet ﷺ asked, "O Messenger of Allah ﷺ! What do you order us to do (in this case)? " He said, "(I order you) to give the rights that are on you and to ask your rights from Allah."  

عَنِ النَّبِيِّ ﷺ قَالَ: «سَتَكُونُ أَثَرَةٌ وَأُمُورٌ تُنْكِرُونَهَا۔» قَالُوا: يَا رَسُولَ اللَّهِ، فَمَا تَأْمُرُنَا؟ قَالَ: «تُؤَدُّونَ الْحَقَّ الَّذِي عَلَيْكُمْ وَتَسْأَلُونَ اللَّهَ الَّذِي لَكُمْ۔»  

I heard Messenger of Allah ﷺ saying, "Allah said, 'If I deprive my slave of his two beloved things (i.e., his eyes) and he remains patient, I will let him enter Paradise in compensation for them.'"  

سَمِعْتُ النَّبِيَّ ﷺ يَقُولُ: «إِنَّ اللَّهَ قَالَ: إِذَا ابْتَلَيْتُ عَبْدِي بِحَبِيبَتَيْهِ فَصَبَرَ، عَوَّضْتُهُ مِنْهُمَا الْجَنَّةَ يُرِيدُ عَيْنَيْهِ۔»  

I asked the Messenger of Allah ﷺ about the plague. He told me that: "It is a Punishment sent by Allah on whom he wills, and Allah made it a source of mercy for the believers, for if one in the time of an epidemic plague stays in his country patiently hoping for Allah's Reward and believing that nothing will befall him except what Allah has written for him, he will get the reward of a martyr."  

سَأَلْتُ رَسُولَ اللَّهِ ﷺ عَنِ الطَّاعُونِ فَأَخْبَرَنِي: «أَنَّهُ عَذَابٌ يَبْعَثُهُ اللَّهُ عَلَى مَنْ يَشَاءُ، وَأَنَّ اللَّهَ جَعَلَهُ رَحْمَةً لِلْمُؤْمِنِينَ: لَيْسَ مِنْ أَحَدٍ يَقَعُ الطَّاعُونُ فَيَمْكُثُ فِي بَلَدِهِ صَابِرًا مُحْتَسِبًا، يَعْلَمُ أَنَّهُ لاَ يُصِيبُهُ إِلاَّ مَا كَتَبَ اللَّهُ لَهُ، إِلاَّ كَانَ لَهُ مِثْلُ أَجْرِ شَهِيدٍ۔»  

the Messenger of Allāh ﷺ said, "˹How˺ wondrous is the affair of a believer: for there is good in every affair of his, while that is not the case with anyone else except in the case of a believer: ˹i.e.,˺ if times of ease strike him, he is grateful which is good for him; and if times of distress strike him, he is patient, which is ˹also˺ good for him."  

قَالَ رَسُولُ اللَّهِ ﷺ «عَجَبًا لأَمْرِ الْمُؤْمِنِ۔ إِنَّ أَمْرَهُ كُلَّهُ خَيْرٌ۔ وَلَيْسَ ذَاكَ لأَحَدٍ إِلاَّ لِلْمُؤْمِنِ۔ إِنْ أَصَابَتْهُ سَرَّاءُ شَكَرَ فَكَانَ خَيْرًا لَهُ، وَإِنْ أَصَابَتْهُ ضَرَّاءُ صَبَرَ فَكَانَ خَيْرًا لَهُ۔»  

"Trials will not cease afflicting the believing man and the believing woman in their self, children, and wealth, until they meet Allah without having any sin."  

قَالَ رَسُولُ اللَّهِ ﷺ: «مَا يَزَالُ الْبَلاَءُ بِالْمُؤْمِنِ وَالْمُؤْمِنَةِ فِي نَفْسِهِ وَوَلَدِهِ وَمَالِهِ حَتَّى يَلْقَى اللَّهَ وَمَا عَلَيْهِ خَطِيئَةٌ۔»  

the Messenger of Allah ﷺ said: "Whoever is tried with something from daughters, and he is patient with them, they will be a barrier from the Fire for him."  

قَالَ رَسُولُ اللَّهِ ﷺ: «مَنِ ابْتُلِيَ بِشَيْءٍ مِنَ الْبَنَاتِ فَصَبَرَ عَلَيْهِنَّ كُنَّ لَهُ حِجَابًا مِنَ النَّارِ۔»  

"When Allah wants good for his slave, He hastens his punishment in the world. And when He wants bad for His slave, He withholds his sins from him until he appears before Him on the Day of Judgement."

And with this (same) chain, (it was reported) from the Prophet ﷺ who said: "Indeed greater reward comes with greater trial. And indeed, when Allah loves a people He subjects them to trials, so whoever is content, then for him is pleasure, and whoever is discontent, then for him is wrath."  

قَالَ رَسُولُ اللَّهِ ﷺ: «إِذَا أَرَادَ اللَّهُ بِعَبْدِهِ الْخَيْرَ عَجَّلَ لَهُ الْعُقُوبَةَ فِي الدُّنْيَا، وَإِذَا أَرَادَ اللَّهُ بِعَبْدِهِ الشَّرَّ أَمْسَكَ عَنْهُ بِذَنْبِهِ حَتَّى يُوَفَّى بِهِ يَوْمَ الْقِيَامَةِ۔»

وَبِهَذَا الإِسْنَادِ عَنِ النَّبِيِّ ﷺ قَالَ: «إِنَّ عِظَمَ الْجَزَاءِ مَعَ عِظَمِ الْبَلاَءِ۔ وَإِنَّ اللَّهَ إِذَا أَحَبَّ قَوْمًا ابْتَلاَهُمْ۔ فَمَنْ رَضِيَ فَلَهُ الرِّضَا، وَمَنْ سَخِطَ فَلَهُ السَّخَطُ۔»
