Battle of Uhud

Allah will not leave the believers as they are without distinguishing the wicked from the righteous. Nor will He reveal the unseen to you, but He chooses messengers for this knowledge as He wills. So, believe in Allah and His messengers, if you do, and remain mindful, you will receive a great reward.

3:179It is not (the purpose) of Allah to leave you in your present state till He shall separate the wicked from the good. And it is not (the purpose of) Allah to let you know the Unseen. But Allah chooseth of His messengers whom He will, (to receive knowledge thereof). So believe in Allah and His messengers. If ye believe and ward off (evil), yours will be a vast reward.
