So if they argue with you, say, "I have submitted myself to Allāh [in Islām], and [so have] those who follow me." And say to those who were given the Scripture and [to] the unlearned, "Have you submitted yourselves?" And if they submit [in Islām], they are rightly guided; but if they turn away - then upon you is only the [duty of] notification. And Allāh is Seeing of [His] servants.
Allah bears witness, and verily, Allah is sufficient as a Witness, and He is the Most Truthful and Just Witness there is; His statement is the absolute truth,
أَنَّهُ لاَ إِلَـهَ إِلاَّ هُوَ
(that La ilaha illa Huwa) meaning, He Alone is the Lord and God of all creation; everyone and everything are His servants, creation and in need of Him. Allah is the Most Rich, Free from needing anyone or anything. Allah said in another Ayah,
لَّـكِنِ اللَّهُ يَشْهَدُ بِمَآ أَنزَلَ إِلَيْكَ
(But Allah bears witness to that which He has sent down (the Qur'an) unto you (O Muhammad )) 4:166.
Allah then mentioned the testimony of His angels and those who have knowledge after he mentioned His own testimony,
The Surah began with the confirmation of Divine Oneness and the refutation of Trinity. Answered here are argumentations in which the disbelievers and deniers among the people of the Book persist - even after the truth of Islam has been proved conclusively. The advice against such ongoing. and unnecessary disputations is that the acceptance or rejection of disputers should be of no use to a believer who simply has to declare that he and those with him have entered the fold of Islam being in no doubt about its truth. The Holy Prophet ﷺ was entrusted with the mission of calling the people of the Book, the Jews and Christians, and the disbelievers of Arabia to submit to Allah and embrace Islam which will be for their own good for they will be on the right path. In case they continue to maintain their hostile attitude, the Holy Prophet ﷺ has been comforted here by saying that his duty is only limited to conveying the message of Allah and His commandments. That the message does not seem to get across to them, as they elect to reject rather than accept, should really not be a matter of concern for him. This is something Allah will take care of in His own way for He is in full sight of what His servants are doing.
Tazkirul Quran
Maulana Wahiduddin KhanOn ayahs 19–21
The God of the universe is the One and only God and He likes justice. This assertion is made in all the revealed scriptures which are still in their original form. The vast universe run by its Master through His unseen agents, the angels, is exactly what it ought to be and as perfect as it can be. According to established knowledge, the universe seems to be a completely unitary system. This would indicate that it has a single Planner. Moreover, everything in the universe being in its right place is a proof that its Lord loves justice and righteousness rather than injustice and wrongdoing. Then how can God, who has maintained justice in the vaster universe, allow injustice in human matters? Each and every part of the universe is in a complete state of ‘surrender’, that is, all its functions are performed in accordance with the appointed plan of God. Exactly the same performance is required of man. Man must recognize his Lord and mould his life in accordance with God’s plan. Making anyone else, save God, the centre of his attention or nurturing the thought that God’s judgement can be based on anything other than justice is inconceivable in the present universe.
