Lit., "except him who has...", etc. According to the classical commentators - including some of the most outstanding Companions of the Prophet - the "bond with God" denotes, in this context, the realization of His oneness and uniqueness; for the wider implications of this term, see surah {2}, note [19]. Consequently, as pointed out by Razi, even great sinners may hope for God's forgiveness - symbolically expressed by the right of "intercession" which will be granted to the prophets on Judgment Day (see note [7]on {10: 3}) - provided that, during their life on earth, they were aware of God's existence and oneness.
No one will be allowed to intercede except those who firmly believe in Almighty Allah.
