Martyrdom
If hardship touches you, know that others have faced hardship too. These days of triumph and trial rotate among people so that Allah may distinguish the believers, select martyrs from among you, and expose the wrongdoers.
3:140If ye have received a blow, the (disbelieving) people have received a blow the like thereof. These are (only) the vicissitudes which We cause to follow one another for mankind, to the end that Allah may know those who believe and may choose witnesses from among you; and Allah loveth not wrong-doers.
