Tensions over Raqqa increased when Mani' came of age and took charge of the Banu Numayr between 1044 and 1056. Mani' viewed himself as the rightful heir to Shabib's possessions and sought to retrieve them by force.Heidemann 2005, p. 97. He switched the Numayrids' formal allegiance from the Fatimids to the Seljuq sultan Tughril Beg of Baghdad, who sent Mani' robes of honor and issued a decree granting him Raqqa. In April 1056, after Thimal rejected Mani's demand to withdraw from Raqqa, hostilities broke out between the two sides. By then, Mani' had already seized Harran from his uncles.Sinclair 1990, p. 205.
