1. Allāh set before us Life and death, prosperity and adversity, blessing and cursing; so choose the next life rather than this worldly life that you may have eternal life, you and your descendants. He who follows the Prophet Muhammad, God's last and final messenger, and believes in Allāh 'God' who sent him, will have eternal life, and will not perish. Know that this worldly life is temporary one. But the Home of the Hereafter that is the eternal Life.
2 . That means to do them totally for Allâh’s sake and in accordance with the teachings of Prophet Muhammad.
3. All parts of the universe are well connected and in perfect harmony and coordination. There is no disorder and discordance in the universe, and nothing is disjointed and out of proportion in the creation of Allah. As for birth defects, genetic mutations and other things that we see in the world are part of this great creation, for perfection cannot be noticed except if the opposite is seen, also as a test for humans.
