Postponing sacred months is another act of disobedience by which those who disregard [God] are led astray: they will allow it one year and forbid it in another in order outwardly to conform with the number of God’s sacred months, but in doing so they permit what God has forbidden. Their evil deeds are made alluring to them: God does not guide those who disregard [Him].
The postponing (of a Sacred Month) is indeed an addition to disbelief: thereby the disbelievers are led astray, for they make it lawful one year and forbid it another year in order to adjust the number of months forbidden by Allâh, and make such forbidden ones lawful. The evil of their deeds is made fair-seeming to them. And Allâh guides not the people who disbelieve.
