It is narrated from Sayyidah Umm Salamah (may Allah be pleased with her) that the Messenger of Allah (peace and blessings be upon him) said: "After the worship of idols and the drinking of wine, the first thing my Lord enjoined upon me and forbade me was people quarrelling with one another (taunting one another)."
