"And most certainly shall We try you by means of danger, and hunger, and loss of worldly goods, of lives and of fruits. But give glad tidings unto those who are patient in adversity - who, when calamity befalls them, say, 'Verily, unto God do we belong and, verily, unto Him we shall return.' It is they upon whom their Sustainer's blessings and grace are bestowed."

The Holy Quran, 2:155-157
