When the people took the oath of allegiance to ʿAbdul Malik, ʿAbdullah bin ʿUmar wrote to him: "To Allah's Slave, ʿAbdul Malik, Chief of the believers, I give the Pledge of allegiance that I will listen to and obey Allah's Slave, ʿAbdul Malik, Chief of the believers, according to Allah's Laws and the Traditions of His Apostle in whatever is within my ability; and my sons too, give the same pledge."
بِالسَّمْعِ وَالطَّاعَةِ لِعَبْدِ اللَّهِ عَبْدِ الْمَلِكِ أَمِيرِ الْمُؤْمِنِينَ عَلَى سُنَّةِ اللَّهِ وَسُنَّةِ رَسُولِهِ فِيمَا اسْتَطَعْتُ وَإِنَّ بَنِيَّ قَدْ أَقَرُّوا بِذَلِكَ
