The Messenger of Allah said: "This goodness contains many treasures, and for those there are keys. So glad tidings to the one whom Allah makes a key to good and a lock for evil, and woe to the one whom Allah makes a key to evil and a lock to good."
أَنَّ رَسُولَ اللَّهِ ﷺ قَالَ إِنَّ هَذَا الْخَيْرَ خَزَائِنُ وَلِتِلْكَ الْخَزَائِنِ مَفَاتِيحُ فَطُوبَى لِعَبْدٍ جَعَلَهُ اللَّهُ مِفْتَاحًا لِلْخَيْرِ مِغْلاَقًا لِلشَّرِّ وَوَيْلٌ لِعَبْدٍ جَعَلَهُ اللَّهُ مِفْتَاحًا لِلشَّرِّ مِغْلاَقًا لِلْخَيْرِ
