How many times have you sat around in the masjid or just at home on the cellphone bored? You start a conversation with your friend, and you talk about what you did over the weekend. The conversation slowly starts to die until your friend says;
There are two types of back biting, the haraam and the halaal. I am going to address the haraam. Many Muslim girls and women do not actually realize they are backbiting until it is pointed out. Talking about how messy your sisters hijab looked, how bad her kids are, or how big that pimple was on sister Fatimah's face was are all forms are haraam backbiting. The excuse that, "No, it's not backbiting...I would say it to her face!" So why didn't you say it to her face when you were talking and laughing with her at the masjid on Sunday? Why wait until Tuesday afternoon to say something about it to someone else? The worst form of backbiting is making fun of someone behind their back to make someone else laugh!
O you who believe! Avoid much suspicion, in deeds some suspicions are sins. And spy not neither backbite one another. Would one of you like to eat the flesh of his dead brother? You would hate it (so hate backbiting). And fear God, verily, God is the one who accepts repentance, Most Merciful. (Surah al-Hujurat ayah 12)
