Qurran - Surah 3 Al Imran

This chapter is named after the family of Imran (Joachim), which includes Imran, Saint Anne (wife of Imran), Mary, and Jesus

Regarding the timing and contextual background of the believed revelation (asbāb al-nuzūl), the chapter is believed to have been either the second or third of the Medinan surahs, as it references both the events of the battles of badr and Uhud. Almost all of it also belongs to the third Hijri year, though a minority of its verses might have been revealed during the visit of the Najrān Christian deputation at the event of the mubahala, which occurred around the 10th year of the Hijrah.
