أَلا إِنَّ بَعض الظَنَّ إِثمٌ فَلا تَكُن

ظَنوناً لِما فيهِ عَلَيكَ أَثام

Beware! Some suspicion is a sin, so do not

Suspect anything that would bring blame upon you.

وَإِن ظَنونَ المَرءِ مِثل سَحائِب

لَوامِع مِنها ماطِر وَجهام

And verily, a man's suspicions are like clouds -

Among them is that which rains and that which thunders violently.
