Allah's Protection of His Prophet in the Holy Quran

(137) So if they believe in the same as you believe in, then they have been [rightly] guided; but if they turn away, they are only in dissension, and Allah will be sufficient for you against them. And He is the Hearing, the Knowing.

(70) We had already taken the covenant of the Children of Israel and had sent to them messengers. Whenever there came to them a messenger with what their souls did not desire, a party [of messengers] they denied, and another party they killed.

(74) They swear by Allah that they did not say [anything against the Prophet] while they had said the word of disbelief and disbelieved after their [pretense of] Islam and planned that which they were not to attain. And they were not resentful except [for the fact] that Allah and His Messenger had enriched them of His bounty. So if they repent, it is better for them; but if they turn away, Allah will punish them with a painful punishment in this world and the Hereafter. And there will not be for them on earth any protector or helper.

(95) Indeed, We are sufficient for you against the mockers

(60) And [remember, O Muhammad], when We told you, "Indeed, your Lord has encompassed the people." And We did not make the sight which We showed you except as a trial for the people, as was the accursed tree [mentioned] in the Qur'an. And We threaten them, but it increases them not except in great transgression.

(73) And indeed, they were about to tempt you away from that which We revealed to you in order to [make] you invent about Us something else; and then they would have taken you as a friend.

(36) Is not Allah sufficient for His Servant [Prophet Muhammad]? And [yet], they threaten you with those [they worship] other than Him. And whoever Allah leaves astray - for him there is no guide.

(48) And be patient, [O Muhammad], for the decision of your Lord, for indeed, you are in Our eyes. And exalt [Allah] with praise of your Lord when you arise.
