The Prophet ﷺ said, "The most true words said by a poet was the words of Labid." He said, Verily, Everything except Allah is perishable and Umaiya bin As-Salt was about to be a Muslim (but he did not embrace Islam). (Using translation from Bukhārī 3841)
"أَصْدقُ كلمة قالها الشَّاعُر كلمة لبيدٍ: أَلا كلُّ شيء ما خلا الله باطلٌ، وكاد أُمَيَّةُ بن أَبي الصَّلتِ أَنْ يُسْلم" .
