﴿مَا نَنسَخْ مِنْ ءَايَةٍ أَوْ نُنسِهَا نَأْتِ بِخَيْرٍ مِّنْهَا أَوْ مِثْلِهَا أَلَمْ تَعْلَمْ أَنَّ اللَّهَ عَلَى كُلِّ شَيْءٍ قَدِيرٌ - أَلَمْ تَعْلَمْ أَنَّ اللَّهَ لَهُ مُلْكُ السَّمَـوَتِ وَالأَرْضِ وَمَا لَكُم مِّن دُونِ اللَّهِ مِن وَلِيٍّ وَلاَ نَصِيرٍ ﴾
(Know you not that Allah is Able to do all things Know you not that it is Allah to Whom belongs the dominion of the heavens and the earth And besides Allah you have neither any Wali (protector or guardian) nor any helper).
Allah directed His servants to the fact that He alone is the Owner of His creatures and that He does with them as He wills. Indeed, His is the supreme authority and all creation is His, and just as He created them as He wills, He brings happiness to whom He wills, misery to whom He wills, health to whom He wills and ailment to whom He wills. He also brings success to whom He wills and failure to whom He wills. He judges between His servants as He wills, allows what He wills and disallows what He wills. He decides what He wills, there is no opponent for His judgment, and no one can question Him about what He does, while they shall be questioned. He tests His servants and their obedience to His Messengers by the Naskh. He commands a matter containing a benefit which He knows of, and then He out of His wisdom, prohibits it. Hence, perfect obedience is realized by adhering to His commands, following His Messengers, believing in what ever they convey, implementing their commands and avoiding what they prohibit.
The statements of Allah here contain tremendous benefit, prove that the Jews are disbelievers and refute their claim that Naskh does not occur, may Allah curse the Jews. In ignorance and arrogance they claimed that the sound mind stipulates that Naskh does not occur. Some of them falsely claimed that there are divine texts that dismiss the possibility that Naskh occurred.
Imam Abu Ja`far bin Jarir said, "The Ayah means, `Do you not know, O Muhammad, that I alone own the heavens and the earth and that I decide whatever I will in them I forbid whatever I will, change and repeal whatever I will of My previous rulings, whenever I will. I also uphold whatever I will.''
Ibn Jarir then said, "Although Allah directed His statement indicating His greatness towards His Prophet , He also rejected the lies of the Jews who denied that the rulings of the Torah could undergo Naskh. The Jews also denied the prophethood of Jesus and Muhammad, because of their dislike for what they brought from Allah, such as changing some rulings of the Torah, as Allah commanded. Allah thus proclaimed to the Jews that He owns the heavens and earth and also all authority in them. Further, the subjects in Allah's kingdom are His creation, and they are required to hear and obey His commands and prohibitions. Allah has full authority to command the creation as He wills, forbidding them from what He wills, abrogate what He wills, uphold what He wills, and decide whatever commandments and prohibitions He wills.''
I (Ibn Kathir) say that the Jews' dismissal of the occurrence of the Naskh is only a case of their disbelief and rebellion. The sound mind does not deny that there could be a Naskh in Allah's commandments, for He decides what He wills, just as He does what He wills. Further, Naskh occurred in previous Books and Law. For instance, Allah allowed Adam to marry his daughters to his sons and then later forbade this practice. Allah also allowed Nuh to eat from all kinds of animals after they left the ark, then prohibited eating some types of foods. Further, marrying two sisters to one man was allowed for Israel and his children, but Allah prohibited this practice later in the Torah. Allah commanded Abraham to slaughter his son, then repealed that command before it was implemented. Also, Allah commanded the Children of Israel to kill those who worshipped the calf and then repealed that command, so that the Children of Israel were not all exterminated. There are many other instances that the Jews admit have occurred, yet they ignore them. Also, it is a well-known fact that their Books foretold about Muhammad and contained the command to follow him. These texts, in their Books, indicate that the Jews were required to follow the Prophet Muhammad and that no good deed would be accepted from them, unless it conformed to Muhammad's Law. The Prophet brought another Book, - the Qur'an -, which is the last revelation from Allah.
﴿أَمْ تُرِيدُونَ أَن تَسْـَلُواْ رَسُولَكُمْ كَمَا سُئِلَ مُوسَى مِن قَبْلُ وَمَن يَتَبَدَّلِ الْكُفْرَ بِالإِيمَـنِ فَقَدْ ضَلَّ سَوَآءَ السَّبِيلِ ﴾
(108. Or do you want to ask your Messenger (Muhammad ) as Musa (Moses) was asked before (i.e. show us openly our Lord) And he who changes faith for disbelief, verily, he has gone astray from the right way.)
