مَنْ عَمِلَ صَالِحًا مِّن ذَكَرٍ أَوْ أُنثَىٰ وَهُوَ مُؤْمِنٌ فَلَنُحْيِيَنَّهُ حَيَاةً طَيِّبَةً ۖ وَلَنَجْزِيَنَّهُمْ أَجْرَهُم بِأَحْسَنِ مَا كَانُوا يَعْمَلُونَ  

16:97

Whoever does righteousness, whether male or female, while he is a believer - We will surely cause him to live a good life, and We will surely give them their reward [in the Hereafter] according to the best of what they used to do.

الَّذِينَ آمَنُوا وَتَطْمَئِنُّ قُلُوبُهُم بِذِكْرِ اللَّهِ ۗ أَلَا بِذِكْرِ اللَّهِ تَطْمَئِنُّ الْقُلُوبُ

 13:28

Those who have believed and whose hearts are assured by the remembrance of Allah . Unquestionably, by the remembrance of Allah hearts are assured.

Those who have believed and whose hearts become serene through the remembrance of Allah. Certainly, through the remembrance of Allah, hearts become tranquil.

وَمَنْ أَعْرَضَ عَن ذِكْرِي فَإِنَّ لَهُ مَعِيشَةً ضَنكًا وَنَحْشُرُهُ يَوْمَ الْقِيَامَةِ أَعْمَىٰ 

20:124

And whoever turns away from My remembrance - indeed, he will have a depressed life, and We will gather him on the Day of Resurrection blind."

قَالَ: قَالَ رَسُولُ الله ﷺ:

 عَجَباً لأمْرِ الْمُؤْمِنِ إِنَّ أَمْرَهُ كُلَّهُ لَهُ خَيْرٌ، وَلَيْسَ ذَلِكَ لأِحَدٍ إِلاَّ للْمُؤْمِن: إِنْ أَصَابَتْهُ سَرَّاءُ شَكَرَ فَكَانَ خَيْراً لَهُ، وَإِنْ أَصَابَتْهُ ضَرَّاءُ صَبَرَ فَكَانَ خيْراً لَهُ.

رواه مسلم
Prophet Muhammad (peace be upon him) said:

“How amazing are the believer’s affairs; all his affairs are good for him. If good befalls him, he is grateful and that is good for him, and if he is afflicted by calamity he is patient and that is also good for him. This is only for the believer.” [Sahih Muslim]

يَا أَيُّهَا الَّذِينَ آمَنُوا اسْتَعِينُوا بِالصَّبْرِ وَالصَّلَاةِ ۚ إِنَّ اللَّهَ مَعَ الصَّابِرِينَ 

2:153

O you who have believed, seek help through patience and prayer. Indeed, Allah is with the patient.

The Prophet ﷺ said,

“The faith of a servant is not upright until his heart is upright, and his heart is not upright until his tongue is upright.”

Prophet ﷺ,

“Whoever believes in Allah and the Last Day, let him speak goodness or remain silent.”[

.The Prophet ﷺ said

“Verily, at times there is fog over my heart, so I seek the forgiveness of Allah one hundred times in a day.”

Prophet ﷺ said,

Do not get angry.
