Arabic (Original)
حَدَّثَنَا يَحْيَى بْنُ سَعِيدٍ عَنْ عُبَيْدِ اللَّهِ حَدَّثَنِي عَمْرُو بْنُ شُعَيْبٍ عَنْ أَبِيهِ عَنْ جَدِّهِ أَنَّ رَسُولَ اللَّهِ صَلَّى اللَّهُ عَلَيْهِ وَسَلَّمَ قَالَ مَا أَسْكَرَ كَثِيرُهُ فَقَلِيلُهُ حَرَامٌ.
English Translation
Abu al-Nadr narrated to us: Muhammad narrated from Sulayman from Amr ibn Shu'ayb from his father from his grandfather that the Prophet (peace be upon him) said: Whoever is asked by Allah about knowledge he has and conceals it, will be bridled on the Day of Resurrection with a bridle of fire.
