Imam Ahmad recorded from Anas bin Malik that the Messenger of Allah said to Ubayy bin Ka'b, «Verily, Allah has commanded me to recite to you {Those who disbelieve from among the People of the Scripture.}» Ubayy said, “He (Allah) mentioned me by name to you?” The Prophet replied, «Yes.» So he (Ubayy) cried. Al-Bukhari, Muslim, At-Tirmidhi and An-Nasal all recorded this Hadith from Shu'bah.

Mentioning the Situation of the Disbelievers among the People of the Scripture and the Idolators

As for the People of the Scripture, they are the Jews and the Christians, and the idolators are the worshippers of idols and fire among the Arabs and the non-Arabs. Mujahid said, they are not going {to leave} “Meaning, they will not be finished until the truth becomes clear to them.” Qatadah also said the same thing. {until there came to them the Bayyinah.} meaning, this Qur’an. This is why Allah says, {Those who disbelieve from among the People of the Scripture and idolators, were not going to leave until there came to them the Bayyinah.} Then He explains what the Bayyinah is by His saying, {A Messenger from Allah, reciting purified pages.} meaning, Muhammad and the Magnificent Qur’an he recites, which is written down among the most high gathering in purified pages. This is similar to Allah’s statement, In Records held in honor. Exalted, purified, in the hands of scribes (angels). Honorable and obedient. Then Allah says, {Wherein are upright Books.} Ibn Jarir said, “Meaning in the purified pages are Books from Allah that are upright, just and straight. They have no mistakes in them because they are from Allah, the Mighty and Majestic.

The Differing only occurred after the Knowledge came

Allah says, {And the People of the Scripture differed not until after there came to them the Bayyinah.} This is similar to Allah’s statement, And be not as those who divided and differed among themselves after the Bayyinat came to them. It is they for whom there is an awful torment. This refers to the people of those divinely revealed Scriptures that were sent down to the nations that were before us. After Allah established the proofs and evidences against them, they divided and differed concerning that which Allah had intended in their Scriptures, and they had many differences. This is like what has been reported in a Hadith that has many routes of transmission, «Verily, the Jews differed until they became seventy-one sects. And verily, the Christians differed until they became seventy-two sects. And this Ummah will divide into seventy-three sects, and all of them will be in the Fire except one.» They said, “Who are they, O Messenger of Allah?” He replied, «(Those who are upon) what I and my Companions are upon.»

The Command of Allah was merely that They make their Religion solely for Him

Allah says, {And they were commanded not, but that they should worship Allah, making religion purely for Him alone,} This is similar to Allah’s statement, And We did not send any Messenger before you but We revealed to him: La ilaha illa Ana. Thus, Allah says, {Hunafa'} meaning, avoiding Shirk and being truly devout to Tawhid. This is like Allah’s statement, And Verily, We have sent among every Ummah a Messenger (proclaiming): "Worship Allah, and avoid the Taghut (false deities)." A discussion of the word Hunafa' has already been mentioned previously and in Surat Al-An‘am, so there is no need to repeat it here. {and give Zakah,} This is doing good to the poor and the needy. {and that is the right religion.} meaning, the upright and just religion, or the nation that is straight and balanced. {and perform Salah} And this is the best of the physical forms of worship.
