My son! May Allah guide you to the right path and protect you from all sins and mistakes. Remember, your first Islamic duty is to think and ponder deeply about the principles of religion (Usul-e-Deen). Make the foundation of faith strong by forceful arguments, have implicit faith in the Creator of the Universe, prophets and walis. Human being is born from human being. He is not an animal.
This does not mean that man should delve deep into the realm of knowledge and wisdom and continue reading voluminous books. Masoomeen (a.m.s) have also warned against going to deep and I also warn you.
What I mean to say is that you should read such books like ‘Aqaaed–e-Majlisi’ by Allama Majlisi (a.r.). Strengthen your belief by arguments, e.g. to prove the existence of Allah, study the creation of the world and its wonderful objects, and ponder that the creation cannot be any creation without a creator.
Amirul Momeneen Hazrat Ali (a.s) has said in ‘Nahjul Balagah’.
“These people think that this grass is such that no one has grown it! This is such a picture for which there is no painter! These people do not put forward any proof in support for their claim. How I wish they would think that nothing could be created without a creator, or how is it possible to create something without a creator.”
Son! May Allah save you from ‘Shirk’ (equating someone else with Allah). To prove that there is only one God, suffice is to say that if there were more than one god then they would have destroyed the world. Allah has said that if there were two gods, then both the earth and sky would have been destroyed.
Amirul Momeneen Hazrat Ali (a.s) has said :
“If there was another god except Allah, then that god also would have had his messengers and prophets.’
Son! To prove prophethood, suffice is to say that it is imperative for Allah’s mercy, bounty and love that there should be a link between the creator and the creation – someone who can bring his ‘Faiz’ from there; and inform about good and evil, beneficial and harmful, who desists you from evil deeds and encourages you to do good deeds.
