سورة At-Taubah ( The Repentance ) - الآية 7

How can there be a covenant with Allah and with His Messenger for the Mushrikun (polytheists, idolaters, pagans, disbelievers in the Oneness of Allah) except those with whom you made a covenant near Al-Masjid-al-Haram (at Makkah)? So long, as they are true to you, stand you true to them. Verily, Allah loves Al-Muttaqun (the pious - see V. 2:2).
