Why is Islam a complete way of life?

People like Charles Darwin, Sigmund Freud, Hegel and Karl Marx viewed man from various angles. In their search for understanding human nature, some concentrated on the body and its form and shape. So they came to certain conclusions which were body-centered. Some viewed man from the occupation he once followed, and thought of him as an animal subjected for evolution. The thought of some other thinkers fell on human belly and they related everything with it. They found it most important and decided that hunger was the cause of all problems. They thought that once this problem is solved, everything would be alright. Those who viewed man and life through sexuality believed it to be the most important thing and whatever they knew, saw and heard was related to it. They declared that the whole human activity is sex centered and if the restrictions imposed on sex were removed everything would be all right. Some others gave undue importance to spirituality and disregarded the body and its needs. So the people who tried to understand man in the absence of divine revelations were like the proverbial blind men, who tried to understand the elephant in their own partial ways. They arrived at certain conclusions which were imperfect and full of errors.
Those who do not know man cannot understand how man should live. Every individual must possess the basic awareness to understand how he should live in this world. This awareness is achieved only through the divine message. It was religion that taught man about the meaning, objective and destiny of his existence.
The manufacturer knows best about the product he manufactures. To give an example, vehicles work best with the oil, spare parts etc. recommended by the vehicle manufacturer. Even if it is a simple thing like air pressure of the wheels, we follow what the manufacturer says. One might ask why? It is our vehicle. We own it and we use it. Why not use it the way we want? Why not change the air pressure of the wheel depending on our mood that day?
We would not try changing it based on our whims and fancies, because we trust that the vehicle maker knows what is best for the vehicle. We trust the manufacturer of the products even for trivial things, how is it rational to make decisions about our lives without looking for guidance and instructions from our creator, God Almighty?
If I may call human beings a machine, we are the most complex machine on earth due to our emotions and thoughts. Our creator, God, knows exactly what is good for us and has prescribed a way of life which was taught to us by the Messengers of God and the scriptures revealed by Him. Like as The Holy Book Quran revealed in the time of Mohammad The last Messenger. Going away from the guidance of God, would lead to chaos and destruction.
Since Islam was revealed from our creator, God Almighty, it is a complete way of life and therefore addresses all the aspects of human life.
Indeed, the religion in the sight of Allah is Islam.

Value of Respecting Parents in Islam

In today’s rapid-paced life, we often tend to get so busy that we forget our parents’ rights. Family values have significantly dropped in our lives, and our friends often become more important to us than our own relatives. Our parents are the people who provide the most care for us in this world. Unfortunately, most of us often fail to show them the respect they deserve.
In Islam, parents' rights are the most venerable rights after those of God. In several verses of the Holy Book Quran, God makes clear that duty, kindness and gratitude towards parents is an essential part of Islam. However, women in Islam, particularly mothers, have been singled out for the upmost respect and devotion. God Himself tells of the hardships involved in motherhood.
What better can emphasize the good treatment of our parents than the following verse from the Holy Book Quran (interpretation of the meaning) {And your Lord has commanded that you shall not serve (any) but Him, and goodness to your parents. If either or both of them reach old age with you, say not to them (so much as) "Ugh" nor rebuke them, and speak to them in honorable terms} [Quran Al-Israa 17:23]. There are two noteworthy conclusions that may be noticed from this verse. First, Allah the Exalted has called for good treatment of parents immediately after ordering us to worship Him. This proves the importance of being kind to our parents and the elevated status in which Allah (SWT) has placed parents in our lives. Second, He has ordered us not to utter even the least of inappropriate comments to them; thus it is very surprising that some people yell at their parents or even tell them to shut up.
Furthermore, when Mohammad The last Messenger (may peace be upon him) was asked which deed was the best, he replied: “The prayer at its appointed hour”. He was asked: “Then what?”, to which he replied: “Kindness to the parents”. Again he was asked: “Then what?”. He replied: “Earnest struggle (Jihad) in the cause of Allah [Muslim].”
Whether or not you live with your parents, or if both of them are still alive, here are some tips to a good relationship with them: If you live with your parents bring something home every now and then. For example, buy them a gift or a cake whenever you receive your paycheck.
Make sure to spend time with them every day, whether it is for reciting Qur’an or reading hadiths together, conducting household chores, or just plain friendly talk. Take them out for picnic. Obeying whatever they ask you to do, as long as it complies with Islam.
If you don’t live with your parents Visit them regularly -- say once a week or every two weeks. If you are unable to visit them often because you live far away for example, then do the next best thing and call them frequently. Also, you may send them letters, and don’t forget greeting cards on Islamic occasions (Ramadan, Eid, etc.) .In the authentic Hadith, a man came to the Prophet (may peace be upon him) and asked him whether he can do any good for his parents after they passed away. The Prophet (peace be upon him) told him to do the following:
- Supplication and istighfar for them,
- Executing their will,
- Connecting with relatives that are likely to be cut with the parents’ death, and
- Honoring their friends
Difficulties with parents:
Reverts to Islam often tend to face difficulties with their non-Muslim parents. Likewise, Muslims who take up new acts of worship (such as growing a beard or wearing hijab) might get into unpleasant situations with them. Although one should not abandon such acts of worship in order to obey one’s parents, one should still retain a good relationship with both parents and treat them kindly. Allah the Exalted has ordered us to obey our parents even if they are non-Muslims – but, once again, as long as what they ask complies with Islam. Conditions such as this require a good deal of patience and can be considered opportunities to show your parents that your newly-found beliefs have actually made you better and closer to them.
