عثمان بن عفان
Muhammad proceeded towards Najd at the head of 400 or 700 men. In his absence, he mandated the affairs of Medina to Abu Dhar al-Ghifari (or according to Umayyad tradition, Uthman ibn Affan). The Muslim fighters penetrated deep into their land until they reached a spot called Nakhla, where they came across some bedouins of Ghatfan.
