﴿ قُلْ يَٰعِبَادِ ٱلَّذِينَ ءَامَنُوا۟ ٱتَّقُوا۟ رَبَّكُمْ ۚ لِلَّذِينَ أَحْسَنُوا۟ فِى هَٰذِهِ ٱلدُّنْيَا حَسَنَةٌۭ ۗ وَأَرْضُ ٱللَّهِ وَٰسِعَةٌ ۗ إِنَّمَا يُوَفَّى ٱلصَّٰبِرُونَ أَجْرَهُم بِغَيْرِ حِسَابٍۢ ﴾
“Say: “[Thus speaks God:] ‘O you servants of Mine who have attained to faith! Be conscious of your Sustainer! Ultimate good awaits those who persevere in doing good in this world. And [remember:] wide is God’s earth, [and,] verily, they who are patient in adversity will be given their reward in full, beyond all reckoning!’””
