"And be not weak-hearted, nor grieve, and you will have the upper hand if you are believers. If a wound has afflicted you, a wound like it has also afflicted the (disbelieving) people. And We bring these days to men by turns, that Allah may know those who believe and take witnesses from among you. And Allah loves not the wrongdoers, And that He may purge those who believe and deprive the disbelievers of blessings. Do you think that you will enter the Garden while Allah has nor yet known those from among you who strive hard (nor) known the steadfast? And certainly you desired death before you met it. So indeed you have seen it now while you look (at it)."
