It is narrated from Sayyiduna Nasr bin Dahar that while going towards Khaybar, he heard Amir bin Akwa’, who was the uncle of Salamah bin Umrah and whose real name was Sinan, reciting poetry to the Prophet (ﷺ). The Prophet (ﷺ) said: "Amir, dismount from your ride and recite for us some of your Huda poetry." So he dismounted and began to recite these verses: "By Allah, if it were not for Allah, we would not have been guided, nor would we have given charity or performed prayer. We are those people that when a nation rebels against us and intends mischief and corruption, we reject it. O Allah, send down tranquility upon us, and if we encounter the enemy, grant us steadfastness."
