Hadith on Hereafter: If people knew what was with Allah

Abu Huraira reported: The Messenger of Allah, peace and blessings be upon him, said, If the believer knew what was with Allah of punishment, no one would hope for Paradise. If the disbeliever knew what was with Allah of mercy, no one would despair of attaining Paradise.”

عَنْ أَبِي هُرَيْرَةَ أَنَّ رَسُولَ اللَّهِ صَلَّى اللَّهُ عَلَيْهِ وَسَلَّمَ قَالَ لَوْ يَعْلَمُ الْمُؤْمِنُ مَا عِنْدَ اللَّهِ مِنْ الْعُقُوبَةِ مَا طَمِعَ فِي الْجَنَّةِ أَحَدٌ وَلَوْ يَعْلَمُ الْكَافِرُ مَا عِنْدَ اللَّهِ مِنْ الرَّحْمَةِ مَا قَنَطَ مِنْ الْجَنَّةِ أَحَدٌ
