Al-Hasan al-Basri (may Allaah have mercy on him) said: “Do not resent the calamities that come and the disasters that occur, for perhaps in something that you dislike will be your salvation, and perhaps in something that you prefer will be your doom.”
Al-Fadl ibn Sahl said: “There is a blessing in calamity that the wise man should not ignore, for it erases sins, gives one the opportunity to attain the reward for patience, dispels negligence, reminds one of blessings at the time of health, calls one to repent and encourages one to give charity.
Through calamity the believer seeks reward, and there is no way to attain it but patience, and there is no way to be patient except with resolute faith and strong will.
