Shaykhul Islām ibn Taymiyyah on Importance of Speaking with Knowledge

قال شيخ الإسلام ابن تيمية رحمه الله: ومن تكلم في الدين بلا علم كان كاذباً وإن كان لايتعمد الكذب

Shaykhul Islām ibn Taymiyyah (may Allāh have mercy upon him) said:

“Whoever speaks about the religion [al-Islām] without knowledge is a liar. Even if he had not intended to lie.”
