An āyah (Arabic: آية, Arabic pronunciation: [ʔaː.ja]; plural: آيات ʾāyāt) is a "verse" in the Quran, one of the statements of varying length that make up the chapters (surah) of the Quran and are marked by a number. In the Quranic context the word means "evidence", "sign" or "miracle", and in Islam may refer to things other than Quranic verses, such as religious obligations (āyat taklīfiyyah) or cosmic phenomena (āyat takwīniyyah). In the Quran it is referred to in several verses such as:

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