“There is no compulsion in religion”
256
According to the reports, in the pre-Islamic period some Medinan women whose children did not survive would vow that if a child lived they would raise him as a Jew; for this reason some children of Ansar families had grown up as Jews among the Banu Nadir. When the Banu Nadir were expelled from Medina, the Ansar said, “We will not leave our children; we will force them to become Muslims.” Thereupon the verse “There is no compulsion in religion” was revealed, and those children who wished were allowed to leave with the tribe, while those who wished could stay.

Revelation context of the surah
Surah-wide
Al-Baqarah was the first surah revealed in Medina, coming down in portions over an extended period beginning in the first years after the Hijra. Its main context is the founding of the Muslim community in Medina, relations with the People of the Book (especially the Jewish tribes), the conduct of the hypocrites, and the change of the qibla (2 AH). It contains foundational legislation on fasting, pilgrimage, family law and the prohibition of usury; the usury verses are reported to be among the last revealed.
