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
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
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
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
We used to take the oath of allegiance to the Prophet ﷺ to hear and obey, and he would tell: In What I am able. (Using translation from Abū Dāʾūd 2940)
بَايَعْتُ النَّبِيَّ ﷺ عَلَى السَّمْعِ وَالطَّاعَةِ فِيمَا اسْتَطَعْتُ
[Machine] By listening and obeying according to the way of Allah and the way of His Messenger ﷺ to the best of my ability.
بِالسَّمْعِ وَالطَّاعَةِ عَلَى سُنَّةِ اللهِ وَسُنَّةِ رَسُولِهِ ﷺ فِيمَا اسْتَطَعْتُ
