Allah has sent down both the disease and the cure
Abu ad-Darda, may Allah be pleased with him, narrated that
The Prophet, may the peace and blessings of Allah be upon him, said: Allah has sent down both the disease and the cure, and He has appointed a cure for every disease, so treat yourselves medically, but use nothing unlawful.
The commands and prohibitions in the book of Allah and the Sunnah of his Prophet express our reality as the truest expression, match the requirements of our lives in perfect conformity, and meet the aims of the worldly life as well as the Hereafter in an easy manner and a strong approach.
The Qur'an and the Sunnah are a clearly defined approach, and a white way whose night is the same as its day. He who learns the rulings of Islam must acknowledge that it is a wise legislation, the legislators cannot bring the like of it, and that many of the intelligent minds, that are limited to the sciences of the world, could not realize the its wisdom; hence we cannot dispense with the worldly sciences and refrain from seeking the religious knowledge.
Islam, by its realistic method, destroys the popular myths among the ignorant of the Arabs and the like. The clear argument and the clear proof respond to every suspicion that the Devil insinuates to his followers, whether they are false liars or they are among those who pretend to be of the righteous people.
