Āyah

A 16th-century Quran opened to show sura (chapter) 2, ayat (verses) 1–4.

Ayah (Arabic: آية āyah, plural آيات āyāt); is the Arabic word for omen, sign, proof, commandment, law, rule and/or guidance. The word is usually used to refer to a verse of the Qur’an. An ayah is the smallest unit of the Qur’an; Muslims believe that each of the 6236 ayah of the Qur’an is a sign from God (called Allāh in Arabic). Chapters in the Qur’an, called surah in Arabic, are made up of several ayahs, though a sura may vary greatly in length, ranging from 3 to 286 ayahs. such as:

تِلْكَ آيَاتُ ٱللَّٰهِ نَتْلُوهَا عَلَيْكَ بِٱلْحَقِّۖ فَبِأَيِّ حَدِيثٍۭ بَعْدَ ٱللَّٰهِ وَآيَاتِهِۦ يُؤْمِنُونَ
"These are the Ayahs of God that We recite for you in truth. So what discourse will they believe after God and His Ayahs?"
