Tuhlaya himself took up a position somewhere to the rear of his centre, under the pretext of seeking guidance from Allah whilst the battle raged, keeping a camel near him in case of retreat.
After some more time, Khalid managed to make dents into his foe's centre, although the ground was more bitterly given by Uyaina's Banu Hazari.
After another two rounds of asking Tuhlaya's advice - to no avail - Uyaina suspected his master of falsehood, and immediately ordered the Banu Hazari to withdraw from the field.
Khalid personally led a column north, overtaking a largely intact part of the routed army 60 miles out at Ghamra, commanded by Uyaina and composed of his Banu Hazari.
He later asked for forgiveness from Caliph Abu Bakr, who forgave him but he was, along with his tribe, banned from joining in any external campaigns as they had indulged in apostasy and so couldn't be trusted.
