How can the idolaters have a pact with God and His Messenger — they cannot —while they disbelieve in God and His Messenger, acting treacherously; except for those with whom you made a pact at the Sacred Mosque?, the day of al-Hudaybiyya — these were Quraysh, for whom an exception was made earlier [Q. 9:4]. So long as they are true to you, keeping to the pact and not breaking it, be true to them, by fulfilling it (fa-mā, ‘so long as’: the mā is a conditional particle). Truly God loves the God-fearing: the Prophet (s) had kept to the pact made with them until they broke it by supporting the Banū Bakr against Khuzā‘a.
