Overall meaning : Allah Almighty states that the idolaters who associate partners with Allah have exchanged Allah’s revelations for paltry worldly gains, refused to accept and follow the truth, prevented others from following Islam and striven hard to dissuade those who converted to Islam from following the truth. If they prevail against a believer, they respect with regard to him neither Allah, nor kinship nor any treaty whatsoever, and it is they who transgress Allah’s bounds and oppress people.
Then, addressing the faithful, He says: If those who associate partners with Allah repent, duly perform the prescribed prayers and pay zakat to those eligible for it, then they are your brothers in faith and fellow Muslims, and We make Our revelations clear for people endowed with knowledge. If, however, they break their solemn pledges after having concluded a covenant with you, revile and disparage your religion, then fight the leaders of unbelief—for they have no regard for binding pledges—so that they may desist from unbelief and misguidance.
