So up I crept, and, to and behold!
I saw that both of them were lame. "
In Islam, there has been much emphasis on the necessity of promoting brotherhood and friendship with the people of faith and the people of good will and at the same time combating against the evil, corruption and the oppressors. Of course, in Islam love is universal and the Prophet of Islam was not sent, "save as a mercy unto all beings" (The Qur'an 21: 107). Therefore, even fighting against those who do wrongs and injustice should be out of love. It is an act of genuine love for mankind as a whole and even, say, for a murderer such as Hitler to fight against him, to punish him and, if needed, to destroy him. Otherwise, he would do more crimes and would degrade himself more and more and would suffer much more sever punishments in this world and hereafter. There is a beautiful story that once an oppressing ruler asked a pious person to pray for him. In response, that pious person asked God not to let him live anymore. That oppressor was shocked and said: " I asked you to pray for me and not against me!" He replied: " This is exactly what I did. It is much better for you and, of course, for the people as well that your life becomes shorter. You will then have less chance to add to your crimes and people will have more chance to rest."
A rational and intelligent love is the one that involves the good and interest of the mankind and not a limited number of people. One can do many things to bring good to individuals or groups which bring evil to society or mankind as a whole. For example, if a judge releases a guilty criminal he might have done something good to that person, but a great harm has been inflicted upon the society and the ideal of justice. One should not let his affections hide the truth. If our beloved child needs injection or operation we should not let our love and passions for him to prevent us from doing so.
According to Islam, love has to be enlightened. A sacred love is the love which is realistic and insightful. It has been a common theme in moral advises by great Muslim preachers and Sufi masters that one should not let one's love for something or some person make him negligent of the whole truth. The reason for this emphasise is that love naturally tends to make the lover "blind and deaf'. If you love some one it is very unlikely to have an impartial view of it, unless the love is directed by the reason. This is why even Sufi Muslims try not to be overwhelmed by love. Siraj ed‑Din writes:
The Sufi has no choice but to be vigilant, observant, and discerning, to put everything in its rightful place, and to give everything its due . ... It is in virtue of this perspective that Sufism is a way of knowledge rather than a way of love. As such it tends to repudiate partialities which the perspective of love necessarily condones and even encourages. [9]
According to Islam, the minimum expectation from believers is that God should have the first place in their heart, in the sense that no other love may override one's love for God; God should be the highest and foremost object of love. The Qur'an says:
Say: If your father or your sons or your brethren or your wives or your kinsfolk or the property you have acquired or the commerce you fear may slacken or the dwellings which you love if these are dearer to you than God and His Apostle and striving in His way, then wait till God brings about His command; God does not guide the transgressing people. (9:24)
This verse clearly indicates that one's love for God has to be superior to one's love for whatever else that one may come to love in one's life. This superiority shows itself when the love for God and for His religion comes in conflict with one's love for one's personal belongings. In this case, a believer should be able to sacrifice his personal favourite things for the sake of God. For example, if God asks us to give our lives to protect innocent lives or our territorial integrity or the like, we should not let our love for the easy life or being with the family and so on prevent us from striving in His way.
Therefore, a believer is not the person who just loves God. A believer is the person whose love for God is the highest and strongest love he has. Elsewhere, the Qur'an says:
Yet there are some people who adopt rivals instead of God, whom they love just as they (should) love God. Those who believe are firmer in their love of God ... (2:165)
Why should one love God? According to Islam, one reason for loving God lies in the fact that God is the most precious, the most perfect and the most beautiful being, that a man can ever conceive and therefore, man out of his nature that aspires to values, beauty and perfection loves God.
Many Islamic scholars, especially mystics have asserted that everybody feels in his heart a great love for God the Almighty without necessarily being aware of it. They argue that even unbelievers who are just after secular aims or ideals love and worship what they take to be the ultimate good. For example, those who want to possess power want to have the ultimate power. They will never be satisfied by becoming a mayor or even president. Even if they could control the whole globe they would think about controlling other planets. Nothing in the world can set their hearts at rest. As soon as people reach what they had set up as their ideals, they realise that it is not sufficient and they will seek for more. Islamic mystics, such as Ibn Arabi inspired by the Qur'an believe that the reason behind this phenomenon is that everybody in fact is seeking towards the ultimate good, that is, God. The Qur'an says: "O man! Surely you strive (to attain) to your Lord, a hard striving until you meet Him." (84:6). However, the fact is that many people make a mistake in recognising what is the highest good. Some might take money as the highest good or, in other words, as their god.
Others might take political power as their god, and so on. The Qur'an says: "Have you seen him who takes his low desires for his god?" (25:43; 45:23)
If it happens that they reach what they have set up as their ideal their innate love for God, the highest good will remain unresponsive and so they will feel unhappy and frustrated. Ibn Arabi says:
"Nothing other than God has been ever loved. It is God who has manifested Himself in whatever is beloved for the eyes of those who love. There is no being except that it loves. Thus, the whole universe loves and is loved and all these go back to Him just as nothing has ever been worshipped other than Him, since whatever a servant (of God) has ever worshipped has been because of wrong imagination of deity in it; otherwise it would have never been worshipped. God, the most High, says (in the Qur'an): `and your Lord has commanded not to worship but Him.'(17:23) This is the case with love as well. No one has ever loved anything other than his Creator. However, He, the most High has hidden Himself from them under the love for Zaynab, Su'ad, Hind. Layla, dunya (this world), money, social position and all other beloved subjects in the universe. [10]
Ibn Arabi adds that: "mystics have never heard any poem or praise or the like but about Him (and they saw Him) beyond veils." [11]
The other reason for loving God is to reciprocate His love and blessings. There is a rich literature in Islamic sources on different aspects and manifestations of God's love and favour for all human beings, including, in a sense, wrongdoers arid those who disbelieve in Him. Human beings love whoever does good to them, and they appreciate such favour and benevolence and feel obliged to be thankful. The Prophet said:
Love God because He has done good to you and He has bestowed favours upon you. [12]
