«إن أعظم الناس عند الله فرية: لرجل هاجى رجلا فهجا القبيلة بأسرها، ورجل انتفى من أبيه وزنى أمه»
The Prophet (peace and blessings be upon him) said:
"Indeed, the greatest slanderer among people in the sight of Allah is a man who satirises (disparages) another man and then disparages his entire tribe, and a man who disowns his own father and accuses his own mother of fornication."
