Al-Haqq (The Truth) — 99 Names of Allah

📖 In the Qur'an

22:6 Surah Al-Hajj

ذَٰلِكَ بِأَنَّ ٱللَّهَ هُوَ ٱلْحَقُّ وَأَنَّهُۥ يُحْىِ ٱلْمَوْتَىٰ وَأَنَّهُۥ عَلَىٰ كُلِّ شَىْءٍ قَدِيرٌ

That is because Allah is the Truth and because He gives life to the dead and because He is over all things competent

Al-Haqq is Reality itself — everything else, however solid it appears, is temporary by comparison.
