Joseph's brothers return to their father, Jacob 12:80-87
12:80 When they despaired of him, they went in private to confer together. The eldest said, 'Do you not know that your father took a pledge from you in the Name of Allah, and that you failed before regarding Joseph? I shall never stir from this land until my father gives me leave or Allah makes known to me His judgement, He is the Best of judges.
12:81 Return, all of you to your father and say to him, "Father, your son has committed a theft. We testify only to what we know. How could we guard against the unforeseen?
12:83 'No' he (Jacob) said, 'your souls have tempted you to do something. But come sweet patience. Allah may bring them all to me. He alone is the Knowing, the Wise.'
