عَنْ أَبِي هُرَيْرَةَ رَضِيَ اللَّهُ عَنْهُ عَنِ النَّبِيِّ صَلَّى اللَّهُ عَلَيْهِ وَآلِهِ وَسَلَّمَ أَنَّهُ قَالَ عَلَى الْمِنْبَرِ أَشْعَرُ بَيْتٍ وَفِي رِوَايَةٍ أَصْدَقُ بَيْتٍ قَالَتْهُ الْعَرَبُ أَلَا كُلُّ شَيْءٍ مَا خَلَا اللَّهَ بَاطِلٌ وَكَادَ أُمَيَّةُ بْنُ أَبِي الصَّلْتِ أَنْ يُسْلِمَ
Sayyiduna Abu Hurairah (may Allah be pleased with him) narrates that the Messenger of Allah (peace and blessings be upon him) said from the pulpit: The truest verse of poetry ever spoken by the Arabs is: "Ala kullu shay'in ma khala Allah batil" (Be aware! Everything besides Allah Almighty is falsehood), and it was near that Umayyah bin Abi Salt would have become Muslim.
