I Don’t Bear Witness

Once a man went to the Prophet (sal Allahu alaihi wa sallam) and requested him to bear witness that he had given his child a gift of an orchard. The Prophet (sal Allahu alaihi wa sallam) asked him, “Do you have another child?” The man said, “Yes.” The Prophet (sal Allahu alaihi wa sallam) asked, “Have you given him an equal gift?” “No,” replied the man. The Prophet (sal Allahu alaihi wa sallam) then said, “I do not bear witness to an injustice.” [Sahih Muslim]

Treat all your children equitably. Favouring one over the other provokes destructive jealousies. Don’t ruin the harmony in your house with your own hands.

Also keep in mind the rule not to bear witness to an injustice. Don’t be a part of any injustice or you will also get a share of the sin. Don’t help any injustice to happen or approve of it, even by silence.
