"The people were along with the Prophet ﷺ on the day of Al-Hudaibiya spreading in the shade of the trees. Suddenly the people surrounded the Prophet ﷺ and started looking at him." ʿUmar said, "O ʿAbdullah! Go and see why the people are encircling Allah's Apostle and looking at him." ʿAbdullah bin ʿUmar then saw the people giving the Pledge o allegiance to the Prophet. So he also gave the Pledge of allegiance and returned to ʿUmar who went out in his turn and gave the Pledge of allegiance to the Prophet.'  

أَنَّ النَّاسَ كَانُوا مَعَ النَّبِيِّ ﷺ يَوْمَ الْحُدَيْبِيَةِ تَفَرَّقُوا فِي ظِلاَلِ الشَّجَرِ فَإِذَا النَّاسُ مُحْدِقُونَ بِالنَّبِيِّ ﷺ فَقَالَ يَا عَبْدَ اللَّهِ انْظُرْ مَا شَأْنُ النَّاسِ قَدْ أَحْدَقُوا بِرَسُولِ اللَّهِ ﷺ فَوَجَدَهُمْ يُبَايِعُونَ فَبَايَعَ ثُمَّ رَجَعَ إِلَى عُمَرَ فَخَرَجَ فَبَايَعَ
