Tawhid, The Unity of God from the Holy Qur'an

Surah Al-Imran, n.3

اللَّهُ لَا إِلَٰهَ إِلَّا هُوَ الْحَيُّ الْقَيُّومُ

Allah, (there is) no god but He, the Everliving[^1], the Self-subsisting by Whom all things subsist[^2] (3:2)

إِنَّ اللَّهَ لَا يَخْفَىٰ عَلَيْهِ شَيْءٌ فِي الْأَرْضِ وَلَا فِي السَّمَاءِ

Allah - surely nothing is hidden from Him in the earth or in the heaven (3:5)

هُوَ الَّذِي يُصَوِّرُكُمْ فِي الْأَرْحَامِ كَيْفَ يَشَاءُ ۚ لَا إِلَٰهَ إِلَّا هُوَ الْعَزِيزُ الْحَكِيمُ

He it is Who shapes you in the wombs as He likes; there is no god but He, the Mighty, the Wise (3:6)

شَهِدَ اللَّهُ أَنَّهُ لَا إِلَٰهَ إِلَّا هُوَ وَالْمَلَائِكَةُ وَأُولُو الْعِلْمِ قَائِمًا بِالْقِسْطِ ۚ لَا إِلَٰهَ إِلَّا هُوَ الْعَزِيزُ الْحَكِيمُ

Allah bears witness that there is no god but He, and (so do) the angels and those possessed of knowledge, maintaining His creation with justice[^3]; there is no god but He, the Mighty, the Wise (3:18)
