Al-Baqarah (Arabic: البقرة, “The Heifer” or “The Cow”) is the second and longest chapter (sūrah) of the Quran. It consists of 286 verses (āyāt), 6,201 words and 25,500 letters.
It is a Medinan surah, that is to say that it was supposedly revealed at Medina after the Hijrah, with the exception the verses with regard to riba (interest or usury) which Muslims believe were revealed during the Farewell Pilgrimage, the last Hajj of Muhammad (SAW). In particular, Verse 281 in this chapter is believed to be the last verse of the Quran to be revealed, on the 10th of Dhul al Hijjah 10 A.H., when Muhammad (SAW) was in the course of performing his last Hajj, and only 80 or 90 days later he died.
