Arabic hadith text
وَعَنْ أَبِي هُرَيْرَةَ قَالَ: قَالَ رَسُولُ اللَّهِ صَلَّى اللَّهُ عَلَيْهِ وَسَلَّمَ: «لَوْ يَعْلَمُ الْمُؤْمِنُ مَا عِنْدَ اللَّهِ مِنَ الْعُقُوبَةِ مَا طَمِعَ بِجَنَّتِهِ أَحَدٌ وَلَوْ يُعْلَمُ الْكَافِرُ مَا عِنْدَ اللَّهِ مِنَ الرَّحْمَةِ مَا قَنَطَ من جنته أحد»
Translation
Abu Hurayrah reported that the Messenger of God (peace be upon him) said: ‘If the believer knew what punishment God has, no one would aspire to His Paradise. If the unbeliever knew what mercy God has, no one would despair of His Paradise.’ Agreed upon. The Arabic source records it as agreed upon (al-Albani).
