I heard Messenger of Allah ﷺ as saying: The truest word which the poet stated is the word of Labid: "Behold! apart from Allah everything is vain."
سَمِعْتُ رَسُولَ اللَّهِ ﷺ يَقُولُ إِنَّ أَصْدَقَ كَلِمَةٍ قَالَهَا شَاعِرٌ كَلِمَةُ لَبِيدٍ أَلاَ كُلُّ شَىْءٍ مَا خَلاَ اللَّهَ بَاطِلٌ مَا زَادَ عَلَى ذَلِكَ
