When the people took the oath of allegiance to ‘Abdul Malik, ‘Abdullah bin ‘Umar wrote to him:
“To Allah’s Slave, ‘Abdul Malik, Chief of the believers, I give the Pledge of allegiance that I will listen
to and obey Allah’s Slave, ‘Abdul Malik, Chief of the believers, according to Allah’s Laws and the Tra –
