How it is used
والله is one of the most common oath expressions in Arabic, used in both classical and everyday speech to swear to or emphasize the truth of what one is saying, roughly like English "I swear to God." It sits alongside other invocations of the same root, such as اللّٰهُمَّ, used when addressing or calling on God directly.
Words from the same root
- إِلٰه a god; any object of worship or adoration
- اللّٰه God; the proper name of the one true deity, held by the lexicographers to derive from ilāh
- اَللّٰهُمَّ "O Allah!" — a vocative form used in supplication and emphatic address
- أَلَهَ he served, worshipped, or adored (a deity)
- تَأَلَّهَ he devoted himself to religious worship or acts of devotion
- إِلٰهِىّ divine; of or relating to God
- الإِلٰهِيَّة theology; the study of God's being and attributes

قال أبو بكر رضي الله عنه فوالله إنا لنلقى مثل هذا،
Abu Bakr, may Allah be pleased with him, said: 'By Allah, we experience the same.'
فَوَاللهِ By Allah
This stacks 'so' + the oath-particle 'by' + 'God': 'so by God!'. The 'wa-' here is not 'and' but the particle of swearing an oath, and it forces the divine name into the genitive. Abu Bakr swears to confirm his words.
قال يقولون لا والله يا رب ما رأوها
He said: They say: No, by Allah, O Lord, they have not seen it.
وَاللَّهِ by Allah
The oath-particle 'by' plus 'God' — 'by God!'. The 'wa-' swears the oath and forces the name into the genitive, stressing their honesty.
قال يقولون ولا والله ما رأوها
He said: They say: No, by Allah, they have not seen it.
وَاللَّهِ by Allah
The oath-particle 'by' plus 'God' — 'by God!'. The 'wa-' swears the oath, forcing the name into the genitive, stressing their truthfulness.
