السلام عليكم ورحمة الله وبركاته If we were to excercise assuming the best of your brother, where could be excercise it between 2 people who might have been wronged by each other? Who do we assume the best of in this scenario because automatically we're assuming the worse of the other.

Ustadh AbdulAziz al-Haqqan

Try to fix this, it is as simple as that, or to stop the evil at once, and the matter will become clearer in sha'a Allah.
