Narrated Abu Huraira:
حَدَّثَنَا أَبُو نُعَيْمٍ ، حَدَّثَنَا سُفْيَانُ ، عَنْ عَبْدِ الْمَلِكِ ، عَنْ أَبِي سَلَمَةَ ، عَنْ أَبِي هُرَيْرَةَ ـ رضى الله عنه ـ قَالَ قَالَ النَّبِيُّ صلى الله عليه وسلم " أَصْدَقُ كَلِمَةٍ قَالَهَا الشَّاعِرُ كَلِمَةُ لَبِيدٍ أَلاَ كُلُّ شَىْءٍ مَا خَلاَ اللَّهَ بَاطِلٌ وَكَادَ أُمَيَّةُ بْنُ أَبِي الصَّلْتِ أَنْ يُسْلِمَ ".
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).
