“If the believer knew what is with Allah of punishment, none would hope for Paradise, and if the disbeliever knew what is with Allah of mercy, none would despair of (attaining) Paradise.”

أَنَّ رَسُولَ اللَّهِ ﷺ قَالَ لَوْ يَعْلَمُ الْمُؤْمِنُ مَا عِنْدَ اللَّهِ مِنَ الْعُقُوبَةِ مَا طَمِعَ فِي الْجَنَّةِ أَحَدٌ وَلَوْ يَعْلَمُ الْكَافِرُ مَا عِنْدَ اللَّهِ مِنَ الرَّحْمَةِ مَا قَنَطَ مِنَ الْجَنَّةِ أَحَدٌ
