add anything to it, diminish anything from it, or alter it. Allah Most High says: “Falsehood cannot approach it from before it or from behind it” (Fussilat 42). Falsehood here means Iblis: he is unable to add to it anything that is not part of it, or to remove from it anything that is part of it.
It was also said that the pronoun in lahu (“it” or “him”) refers to Muhammad, peace and blessings be upon him; that is: We surely protect Muhammad from whoever intends him harm, as He, exalted is His remembrance, says: “And Allah will protect you from the people” (al-Ma’idah 67).
“And We certainly sent messengers before you among the communities of former peoples. (10) No messenger came to them without their ridiculing him. (11) Thus We cause it to enter the hearts of the criminals. (12) They do not believe in it, although the way of the former peoples has already passed. (13) Even if We opened for them a gate in the heaven and they continued ascending through it, (14)”
His saying, Most High: “And We certainly sent before you”—that is, messengers—“among the communities of former peoples”: that is, among the nations and generations of the past (1).
A shīʿah is a group of people who gather together and are united in their position (2).
“No messenger came to them without their ridiculing him,” just as they did with you. He mentioned this (3) as a consolation to the Prophet, peace and blessings be upon him.
“Thus We cause it to enter”: just as We caused disbelief, denial, and ridicule of the messengers (4) to enter the hearts of the communities of former peoples, so We cause it to enter—that is, place it (5)—“in the hearts of the criminals,” meaning the idolaters of Mecca, your people. This refutes the Qadariyyah (6).
“They do not believe in it,” meaning that they do not believe in Muhammad, peace and blessings be upon him, or in the Quran. “Although the way of the former peoples has already passed”: that is, Allah Most High’s precedent of destroying the earlier nations that denied the messengers. This is a warning to the people of Mecca.
“Even if We opened for them”—meaning, for those who say, “Why do you not bring us the angels?”—“a gate in the heaven and they continued ascending through it”: that is, the angels would continue ascending through it while they saw them plainly. This is the view of the majority.
