﴿ وَعَدَ ٱللَّهُ ٱلَّذِينَ ءَامَنُوا۟ مِنكُمْ وَعَمِلُوا۟ ٱلصَّٰلِحَٰتِ لَيَسْتَخْلِفَنَّهُمْ فِى ٱلْأَرْضِ كَمَا ٱسْتَخْلَفَ ٱلَّذِينَ مِن قَبْلِهِمْ وَلَيُمَكِّنَنَّ لَهُمْ دِينَهُمُ ٱلَّذِى ٱرْتَضَىٰ لَهُمْ وَلَيُبَدِّلَنَّهُم مِّنۢ بَعْدِ خَوْفِهِمْ أَمْنًۭا ۚ يَعْبُدُونَنِى لَا يُشْرِكُونَ بِى شَيْـًۭٔا ۚ وَمَن كَفَرَ بَعْدَ ذَٰلِكَ فَأُو۟لَٰٓئِكَ هُمُ ٱلْفَٰسِقُونَ ﴾

“God has promised those of you who have attained to faith and do righteous deeds that, of a certainty, He will cause them to accede to power on earth, even as He caused [some of] those who lived before them to accede to it; and that, of a certainty, He will firmly establish for them the religion which He has been pleased to bestow on them; and that, of a certainty, He will cause their erstwhile state of fear to be replaced by a sense of security [seeing that] they worship Me [alone], not ascribing divine powers to aught beside Me. But all who, after [having understood] this, choose to deny the truth - it is they, they who are truly iniquitous!”

The promise of the grant of a dominant status applied initially to the Prophet Muhammad and his companions, but it also applies to the whole community of the believers. It is observed here that men of faith need not make the possession of power and dominance their target, for these are actually blessings of God, conferred upon deserving believers as a reward for their faith and good deeds. The purpose of granting this dominant status is to provide the believers with stability in this world, so that they may be able to live peacefully and in safety, lead their lives as the subjects of the One God and pray to Him freely, without fearing their enemies. The dominant status of the people of faith shall continue so long as they remain grateful to God and do not lose their fear of God (taqwa). Appointing a successor, khalifah, or ‘one who comes afterwards’, entails the conferring of dominant status and stability on one community in place of the community, which had earlier enjoyed this position. The dominant position is, in fact, a part of the divine trial. God gives this position to all communities, one after another, and thus puts them to the test. For people of faith, this position is a means of judging them.
