Ibn Abi Dunya’s book Husn
az-Zan Billah contains more than one hundred and fifty texts from the Qur’an
and the Sunnah which entreat the believer to be optimistic, to repudiate
hopelessness, and to strive towards betterment through work. And here is a
promising fact: those revealed texts that promise good for doing righteous
deeds far outnumber those that warn of impending punishment for perpetrating
evil deeds. And Allah, the Exalted, has given to everything its measure.
