﴿ وَإِذَا تُتْلَىٰ عَلَيْهِمْ ءَايَاتُنَا بَيِّنَٰتٍۢ ۙ قَالَ ٱلَّذِينَ لَا يَرْجُونَ لِقَآءَنَا ٱئْتِ بِقُرْءَانٍ غَيْرِ هَٰذَآ أَوْ بَدِّلْهُ ۚ قُلْ مَا يَكُونُ لِىٓ أَنْ أُبَدِّلَهُۥ مِن تِلْقَآئِ نَفْسِىٓ ۖ إِنْ أَتَّبِعُ إِلَّا مَا يُوحَىٰٓ إِلَىَّ ۖ إِنِّىٓ أَخَافُ إِنْ عَصَيْتُ رَبِّى عَذَابَ يَوْمٍ عَظِيمٍۢ ﴾

“AND [thus it is:] whenever Our messages are conveyed unto them in all their clarity, those who do not believe that they are destined to meet Us [are wont to] say, "Bring us a discourse other than this, or alter this one.” Say [O Prophet]: "It is not conceivable that I should alter it of my own volition; I only follow what is revealed to me. Behold, I would dread, were I [thus] to rebel against my Sustainer, the suffering [which would befall me] on that awesome Day [of Judgment]!"”

‘Then We made you their successors (khala’if, sing. khalifah) in the land.’ The real meaning of khalifah is ‘one who comes afterwards’. This word ‘successor’ is specially used for coming into power after another. This succession is in relation to human beings and not in relation to God. In the Quran, wherever the word khilafah has been used, it is in connection with succession to some creature and not in connection with succession to God. Making somebody a successor is solely for the purpose of putting him to the test and is not meant to confer any honour. Making somebody a successor means giving one an opportunity to work after another; it is placing one community in the arena of testing in place of another community. For example, in India, the native Rajas were replaced by Mughals. Then they were removed and the Britishers were made their successors. Later, they (the British) were made to leave the country, making way for the majority community. In all these cases, the ‘one coming afterwards’ was the successor (khalifah) of the earlier one.
