Answered by Shaykh Faraz Rabbani
The reason is because of the English translation of the ayat that I have come across, which mentions that one must ‘avoid most suspicion.’ Could you provide some examples or example of when suspicion is justified.
Walaikum assalam wa rahmatullah,
Suspicion, first, is of two kinds:
a) in one’s beliefs;
b) in one’s actions.
When one has doubts about another, one may exercise caution in one’s actions, but one cannot believe ill of another based on mere suspicions, because doubts cannot lift the operating certainty about others that their affairs are sound.
So, for example, if one sees a shopkeeper doing something doubtful in their dealings, one may have operational caution and avoiding dealing with them. However, one cannot believe that they are involved in the haram.
When circumstances make matters clear, however, one may believe one’s suspicions, though the way of those of scrupulousness is to limit the dislike to the wrongful actions and not persons themselves.
And Allah knows best.
