Arabic (Original)
حَدَّثَنَا ابْنُ نُمَيْرٍ قَالَ حَدَّثَنَا عُمَارَةُ بْنُ زَاذَانَ عَنْ عَلِيِّ بْنِ الْحَكَمِ عَنْ عَطَاءِ بْنِ أَبِي رَبَاحٍ عَنْ أَبِي هُرَيْرَةَ أَنَّ رَسُولَ اللَّهِ صَلَّى اللَّهُ عَلَيْهِ وَسَلَّمَ قَالَ مَنْ سُئِلَ عَنْ عِلْمٍ يَعْلَمُهُ فَكَتَمَهُ أُلْجِمَ يَوْمَ الْقِيَامَةِ بِلِجَامٍ مِنْ نَارٍ.
English Translation
Ibn Numayr told us: 'Umarah ibn Zadhan told us, from 'Ali ibn al-Hakam, from 'Ata' ibn Abi Rabah, from Abu Hurayrah, that the Messenger of Allah, peace and blessings be upon him, said: "Whoever is asked about knowledge he possesses and conceals it will be bridled on the Day of Resurrection with a bridle of fire."
