O you who yearn for eternal beauty, traveler on the path of the true wish, may Allah make you successful in knowing the true way, finding it, and being upon it. May He use you and us in actions that please Him and are done for His sake. For the beginning and the end and what is in between, and success in them all, belong only to Him.
The way and means to eternal salvation and bliss is in coming close to the Truth. Allah Himself teaches us the meaning of His closeness to us. He teaches us by sending us His prophets. We say, "we believe." It is the truth. We accept and confirm it. The only thing then left for us to do is to follow the teachings and the example of His prophet.
First, you must believe in the oneness and uniqueness of the One who is before the before and after the after, who created us and everything else, and you must not associate with Him anything unbefitting the purity of His Essence. He Himself says in His divine book:
If there were in them gods besides Allah, (the heavens and the earth) would both have been in disorder (mixing and clashing and being destroyed).
The wills of many creators would clash and cancel each other, not permitting anything to be or to happen. Therefore, if we and all existence exist, He the One and Unique Creator - exists, and He has no associates.
O you with beautiful nature and pure heart, do not debate, discuss, even talk with people who attribute partners to Allah. There is no use in trying to convince them. Even the deniers will finally concede:
And if you ask them who created the heavens and the earth they will say, Allah.
They as well will finally admit an unknown force as the initial Creator of the creation - but they will add to Him further creators. The difference between them and the believers is that they suppose that others, among the created, are also able to create. You do not have to prove to them the existence of Allah. Let them prove, if they can, the existence of His associates.
This is sufficient advice for you on the subject of professing the oneness of Allah. Time is valuable: you cannot be careless with it. If the mind has reached a state in which it is free from doubt and the heart is safe and secure, it makes no sense to disturb this peace with superfluous proofs.
The second matter of importance for one who wishes to learn is the belief that Allah Most High is free from all resemblance to anything visible or invisible in the creation. He is free from all defect.There are some who, wanting to see the image of their Creator, err, and liken Him to a human being. Let His own words be your guide in this. He says:
Any thought, any word, any qualiy or attribute not corresponding to this principle is a falsehood, unworthy of the Divine. Therefore seek no further than the fact that none resemble or are like Him. That is His reality. This is also confirmed by the declaration of His messenger, who said, "At the beginning was Allah, and none with Him." The ones who followed him added to this statement, "It is now as it was." As it was before the creation, it is after the creation. From the time when matter was hidden under the veil of nonexistence and there was no form, nothing has been added or subtracted. Though He has created the creation, still there are none like Him. Nothing is like Him. Nothing is Him, but everything is from Him. The divine word that He is without likeness cancels all other thoughts, claims, and interpretations.
You must also accept, and believe, even if you do not understand, the allegorical verses of the Holy Qur`an and the ambiguous statement of the Messenger of Allah concerning the unity and the ultimate cause, as well as all the declarations of the prophets which have come to us unaltered. You must consider that the significance of these words is a part of divine knowledge and that as such, you accept them. The monumental meanings of these holy expressions are for the understanding of people who are close enough to Allah to be able to see His beautiful attributes.
There is no better proof of the perfection of the Divine, who is self-existent and whose existence is a necessity for the existence of all else, than the holy verse:
Nothing is like Him
Allah declares with this verse His being, His essence, His divine nature, His limitless greatness, His glory. So write in your heart and mind this principle, this foundation of faith, and believe in Allah`s prophet and the message that he brought from the Divine Truth, and in Allah`s orders and justice. Furthermore, have faith in the true declarations of all the prophets known and unknown. Love their companions; accept the truth of their mission. Do not speak against them. Do not value one over another. Think of them with terms of praise, as they are described in the Holy Qur`an and in the words of other prophets, which can only be the truth. Show respect, as did the prophets, for the character that distinguishes the perfect man, and for holy places. Accept and believe in the deeds and the words of the saints, even though you may not understand their state and the miracles attributed to them.
Look upon the whole creation, and above all, mankind, with good will - accepting, approving, forgiving, serving, loving. Make that your nature in your dealings with the world. Listen to your conscience. Cleanse your heart. In that clean heart, keep up prayer for your faithful brothers. Help and serve, as much as you can, the people who hide their misery, who are content with their poverty, the travelers on the path to truth. Do not attribute to yourself virtue, goodness, and graciousness because of your service to the creation. Consider that you owe other people thanks for having humbly accepted your help. It is incumbent upon you to lighten the load of those who are burdened. If people whose pain you have helped to alleviate cause you pain in return - if their responses, their ways, their habits are dark and cast shadows upon you - show patience and forbearance. Do not forget that Allah says:
surely Allah is with the patient. (Baqara, 153) (By Ibn `Arabi)
