وَيَوْمَ يَحْشُرُهُمْ وَمَا يَعْبُدُونَ مِن دُونِ ٱللَّهِ فَيَقُولُ ءَأَنتُمْ أَضْلَلْتُمْ عِبَادِى هَٰٓؤُلَآءِ أَمْ هُمْ ضَلُّوا۟ ٱلسَّبِيلَ
And on the day when He will assemble them and that which they worship instead of Allah and will say: Was it ye who misled these my slaves or did they (themselves) wander from the way?
Surah Al-Furqaan(25:17)
Sahih al-Bukhari
Military Expeditions led by the Prophet (pbuh) (Al-Maghaazi)
Chapter: The Ghazwa of Al-Hudaibiya
`Abdullah bin `Umar added:
"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." `Umar said, "O `Abdullah! Go and see why the people are encircling Allah's Apostle and looking at him." `Abdullah bin `Umar then saw the people giving the Pledge o allegiance to the Prophet. So he also gave the Pledge of allegiance and returned to `Umar who went out in his turn and gave the Pledge of allegiance to the Prophet.'
