“ Had they been apart, We would surely have chastised those who disbelieved from among them with a painful chastisement.
26 When those who disbelieved harboured disdain in their hearts, the disdain of Ignorance, but Allah sent down His tranquillity on His Messenger and on the believers and made them keep the word of observance of duty, and they were entitled to it and worthy of it. And Allah is ever Knower of all things. ”

“ They say with their tongues what is not in their hearts. Say: Then who can control aught for you from Allah, if He intends to do you harm or if He intends to do you good. Nay, Allah is ever Aware of what you do.
12 Nay, you thought that the Messenger and the believers would never return to their families, and that was made fair-seeming in your hearts, and you thought an evil thought, and you are a people doomed to perish.
13 And whoever believes not in Allah and His Messenger -- then surely We have prepared burning Fire for the disbelievers. ”

“ And were it not for the believing men and the believing women, whom, not having known, you might have trodden down, and thus something hateful might have afflicted you on their account without knowledge -- so that Allah may admit to His mercy whom He pleases. ”
