How many times have you been judgemental and quick in making assumptions only to be proven wrong afterwards.
We see and we judge without looking deeper into situations.
And Astagfirullah many times we are quick in sharing our assumptions with others destroying the good names of others without evidence and ending up slandering or back biting our brothers and sisters.
Islam, asks us to always make a default assumption of the good nature of people, always make the assumption that people are good and do no wrong, that they are innocent of any crime or bad deed (even of lying, back-biting, adultery etc ).
So before we come to hasty conclusions and assumptions we should always remember the words of Prophet Muhammad (peace and blessings be upon him)
