Surah Aal-E-Imran Ayahs #145 Translated in English

And that Allāh may purify the believers [through trials] and destroy the disbelievers.

Or do you think that you will enter Paradise while Allāh has not yet made evident those of you who fight in His cause and made evident those who are steadfast?

And you had certainly wished for death [i.e., martyrdom] before you encountered it, and you have [now] seen it [before you] while you were looking on.

Muḥammad is not but a messenger. [Other] messengers have passed on before him. So if he was to die or be killed, would you turn back on your heels [to unbelief]? And he who turns back on his heels will never harm Allāh at all; but Allāh will reward the grateful.

And it is not [possible] for one to die except by permission of Allāh at a decree determined. And whoever desires the reward of this world - We will give him thereof; and whoever desires the reward of the Hereafter - We will give him thereof. And We will reward the grateful.
