The Battle of Bani Mustaliq
On 19th of the Islamic month of Sha’ban in 6 AH, the Battle of Bani Mustaliq occurred near a place called Muraysi between Jeddah and Rabigh, when on hearing news of the intention of pagan Arabs led by Hareth ibn Abi Dirar, to attack Muslims, Prophet Mohammad (SAWA) led an expedition. The refusal of the Arabs to cease hostilities and heed the call of Islam, resulted in attack on the Muslims, whose strength was not much since the Prophet had only 30 riders with him and his forces also included some hypocrites, many of whom deserted on hearing that most Arab tribes were allied with Hareth.
The Muslims had no other option but to defend themselves with arms. Imam Ali (AS) led the charge and soon disposed off some of the leading pagans such as Malik. The Muslims emerged victorious although some descendants of the Prophet’s grandfather, Abdul Muttalib, were martyred. The fruits of this victory were the capture of several hundred pagan Arabs, including the fearsome Bani Mustaliq chief, Hareth, who later, along with many members of his clan became Muslim.
His daughter Juwaira, who surrendered to Imam Ali (AS) became a Muslim before him and married the Holy Prophet. It was during this expedition that God revealed Surah al-Munafiqoun since some of those who accompanied the Holy Prophet from Madinah and claimed to be Muslims, like Abdullah bin Ubbayy, were hypocrites at heart, planning to undermine Islam.
