Arabic (Original)
حَدَّثَنَا مُحَمَّدُ بْنُ يَزِيدَ أَخْبَرَنَا الْحَجَّاجُ عَنْ عَطَاءٍ عَنْ أَبِي هُرَيْرَةَ عَنْ النَّبِيِّ صَلَّى اللَّهُ عَلَيْهِ وَسَلَّمَ قَالَ مَنْ كَتَمَ عِلْمًا يَعْلَمُهُ جَاءَ يَوْمَ الْقِيَامَةِ مُلَجَّمًا بِلِجَامٍ مِنْ نَارٍ.
English Translation
Muhammad b. Yazid told us: al-Hajjaj informed us, from Ata', from Abu Hurayrah, from the Prophet, peace and blessings be upon him, who said: "Whoever conceals knowledge that he knows will come on the Day of Resurrection bridled with a bridle of fire."
