The following is a chapter from Shaikhul-Islaam Abu Ismaa`eel Al-Harawee’s (rahimahullaah, 396 – 481H): “The Book Of Forty Narrations In The Evidences Of Tawheed”
وَقُلْ جَاءَ الْحَقُّ وَزَهَقَ الْبَاطِلُ ۚ إِنَّ الْبَاطِلَ كَانَ زَهُوقًا
“And say: ‘The Truth has come and falsehood has been vanquished. Surely! Falsehood is ever bound to be wiped out.'” (Al-Israa 17:81)
Chapter (3): The Immense Sin Upon The One Who Conceals Knowledge
Abu Ismaa`eel Al-Harawee (481H) with his chain of narration to Abdullaah Ibn `Amr (radiyallaahu `anhu) that Allaah’s Messenger (salallaahu `alaihi wassallam) said:
“Whoever conceals knowledge Allaah will bridle him with a bridle of fire [on the Day of Resurrection].”
