Bismillaah!
Assalaamu Alaikum Wa Rahmatullahe Wabarakatuh
Knowledge Before Action
Does More Harm Than Good.
Umar ibn Abdul Azees (may Allah have mercy on him) used to say:
مَنْ عَمِلَ فِي غَيْرَ عِلْمٍ
Whoever acts without knowledge
كَانَ مَا يُفْسِدُ أَكْثَرُ مِمَّا يُصْلِحُ
Does more harm than good.
(جَامِعُ الْبَيَانِ الْعِلْمُ وَ فَضْلُ #١٣٢)
