The Prophet ﷺ said, "None will enter Paradise but will be shown the place he would have occupied in the (Hell) Fire if he had rejected faith, so that he may be more thankful; and none will enter the (Hell) Fire but will be shown the place he would have occupied in Paradise if he had faith, so that may be a cause of sorrow for him."
قَالَ النَّبِيُّ ﷺ لاَ يَدْخُلُ أَحَدٌ الْجَنَّةَ إِلاَّ أُرِيَ مَقْعَدَهُ مِنَ النَّارِ لَوْ أَسَاءَ لِيَزْدَادَ شُكْرًا وَلاَ يَدْخُلُ النَّارَ أَحَدٌ إِلاَّ أُرِيَ مَقْعَدَهُ مِنَ الْجَنَّةِ لَوْ أَحْسَنَ لِيَكُونَ عَلَيْهِ حَسْرَةً
