I witnessed Ibn ʿUmar when the people gathered around ʿAbdul Malik. Ibn ʿUmar wrote: I gave 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 as much as I can; and my sons too, give the same pledge.'  

بِالسَّمْعِ وَالطَّاعَةِ لِعَبْدِ الْمَلِكِ أَمِيرِ الْمُؤْمِنِينَ عَلَى سُنَّةِ اللَّهِ وَسُنَّةِ رَسُولِهِ مَا اسْتَطَعْتُ وَإِنَّ بَنِيَّ قَدْ أَقَرُّوا بِمِثْلِ ذَلِكَ  

ʿAbdullah Bin ʿUmar wrote to ʿAbdul Malik bin Marwan, swearing allegiance to him: 'I swear allegiance to you in that I will listen and obey what is in accordance with the Laws of Allah and the Tradition of His Apostle as much as I can.'  

بِالسَّمْعِ وَالطَّاعَةِ عَلَى سُنَّةِ اللَّهِ وَسُنَّةِ رَسُولِهِ فِيمَا اسْتَطَعْتُ  

Malik related to me from Abdullah ibn Dinar that Abdullah ibn Umar wrote to Abd al-Malik ibn Marwan, making an oath of allegiance. He wrote, "In the name of Allah, the Merciful, the Compassionate. To the slave of Allah, Abd al-Malik, the amir al-muminin, Peace be upon you. I praise Allah to you. There is no god but Him. I acknowledge your right to my hearing and my obedience according to the sunna of Allah and the sunna of His Prophet, in what I am able."  

أَنَّ عَبْدَ اللَّهِ بْنَ عُمَرَ كَتَبَ إِلَى عَبْدِ الْمَلِكِ بْنِ مَرْوَانَ يُبَايِعُهُ فَكَتَبَ إِلَيْهِ بِسْمِ اللَّهِ الرَّحْمَنِ الرَّحِيمِ أَمَّا بَعْدُ لِعَبْدِ اللَّهِ عَبْدِ الْمَلِكِ أَمِيرِ الْمُؤْمِنِينَ سَلاَمٌ عَلَيْكَ فَإِنِّي أَحْمَدُ إِلَيْكَ اللَّهَ الَّذِي لاَ إِلَهَ إِلاَّ هُوَ وَأُقِرُّ لَكَ بِالسَّمْعِ وَالطَّاعَةِ عَلَى سُنَّةِ اللَّهِ وَسُنَّةِ رَسُولِهِ فِيمَا اسْتَطَعْتُ  

[Machine] When the people gathered around Abd al-Malik, Abdullah ibn Umar wrote to him, "Peace be upon you. After that, I acknowledge my hearing and obedience to Abdullah, the servant of Allah and the commander of the faithful, according to the Sunnah of Allah and the Sunnah of the Messenger of Allah ﷺ as much as I am able. Indeed, my children have also acknowledged the same. Peace be upon you."  

لَمَّا اجْتَمَعَ النَّاسُ عَلَى عَبْدِ الْمَلِكِ كَتَبَ إِلَيْهِ عَبْدُ اللهِ بْنُ عُمَرَ سَلَّامٌ عَلَيْكَ أَمَّا بَعْدُ فَإِنِّي أُقِرُّ بِالسَّمْعِ وَالطَّاعَةِ لِعَبْدِ اللهِ عَبْدِ الْمَلِكِ أَمِيرِ الْمُؤْمِنِينَ عَلَى سُنَّةِ اللهِ وَسُنَّةِ رَسُولِ اللهِ ﷺ فِيمَا اسْتَطَعْتُ وَإِنَّ بَنِيَّ قَدْ أَقَرُّوا بِمِثْلِ ذَلِكَ وَالسَّلَامُ  

'Abdullah ibn 'Umar wrote to 'Abdu'l-Malik ibn Marwan in order to pledge him his allegiance. He wrote to him, "In the Name of Allah, the All-Merciful, Most Merciful. To 'Abdu'l-Malik, the Amir al-Mu'minin, from 'Abdullah ibn 'Umar. Peace be upon you. I praise Allah to you. There is no god but Him. I offer you obedience according to the sunna of Allah and the sunna of His Messenger as much as I can."  

بِالسَّمْعِ وَالطَّاعَةِ عَلَى سُنَّةِ اللهِ وَسُنَّةِ رَسُولِهِ فِيمَا اسْتَطَعْتُ
