Indeed, everything apart from God is vain.
Quote
Indeed, everything apart from God is vain.
Arabic original
ألا كل شيء ما خلا الله باطل.
What it means
From a religious perspective, worldly things are transient beside God. Vain here concerns their lack of lasting permanence, rather than simply whether an object or activity is useful.
The story behind this quote
This half-line by Labid is reported in al-Bukhari’s Great History. The linked source quotes it in a transmission praising the truth expressed by the poet.
The cited passage is half a verse, explaining its brevity. Transmission in a religious work supplies a particular reading context. The translation keeps the contrast between the world and God; the commentary clarifies that perspective without treating the line as a judgement on every everyday activity.
The source
صدر بيت للبيد، كما رواه البخاري في التاريخ الكبير, باب لبيد؛ ورد في الحديث: «أصدق كلمة قالها الشاعر قول لبيد»
