The danger of speaking without knowledge.
صحبت عبد الله ابن عمر – رضي الله عنه – أربعة و ثلاثين شهراً فكثيرا ما كان يُسأل فيقول : لا أدري ، ثم يلتفت إليَّ فيقول : تدري ما يريد هؤلاء ، يريدون أن يجعلوا ظهورنا جسراً لهم إلى جهنم
’Uqbah bin Muslim said: For 34 years I kept Ibn ’Umar’s company and he used to often say ”I don’t know” (when he was asked about anything).
Whereupon he would turn towards me and say: ”Do you know what these people want? They want to make our backs bridges into the Hellfire (by speaking about Islam without knowledge)!
