What was the last Qur'anic verse received by Muhammad (Sallallahu Alaihi wa Sallam) through Jibreel?

Praise be to Allah, the Lord of the World; and may His blessings and peace be upon our Prophet Muhammad and upon all his Family and Companions.

Scholars of Islam differ concerning the verse that was last revealed. But, according to the predominant opinion, it is: {And be afraid of the Day when you shall be brought back to Allâh. Then every person shall be paid what he earned, and they shall not be dealt with unjustly.} [2:281].
Allah knows best.
