﴿ وَيُبَيِّنُ ٱللَّهُ لَكُمُ ٱلْءَايَٰتِ ۚ وَٱللَّهُ عَلِيمٌ حَكِيمٌ ﴾

“for God makes [His] messages clear unto you - and God is all-knowing, Wise!”

Criticism may therefore be legitimate or illegitimate. While the former is supported by strong arguments, the latter lacks any factual basis and must be refrained from. In practice, when it is an opponent against whom allegations are made, no great need is felt for any further investigation. The allegations are unquestioningly accepted and the story is spread far and wide. This is not only irresponsible, but is also a serious offence, which is punishable both in this world and the world Hereafter.
