Indeed, the postponing [of restriction within sacred months] is an increase in disbelief by which those who have disbelieved are led [further] astray. They make it lawful one year and unlawful another year to correspond to the number made unlawful by Allāh and [thus] make lawful what Allāh has made unlawful. Made pleasing to them is the evil of their deeds; and Allāh does not guide the disbelieving people.
