Spirituality
Spirituality involves the purification of oneself to allow for the liberation of the soul to become full of noor (light).
The beginning of spiritual life is to extricate one's self from natural cravings and urges and to revert to the path of Law, to enter through the door of destiny and progress onward to return to normal urges but yet retaining the spiritual height ascended. So, you should control your urges in matters of food and drink, dress, marital relations, habitation: and tendencies and habits.
10 Rules for Spiritual Advancement Given by Sayyidina Abu Muhammad Muhayuddin A Shaikh Abdul Qadir Al-Jilani Al Hasani Al-Husaini
.
1. Jokingly or seriously, don't lie, because once your tongue avoids lying, Allah the Most High enlarges your chest and purifies your understanding and ilm (knowledge). That person becomes as if they don't know what a lie is. Everything becomes truth to him. When he hears other people lie, the mureed should pray for them not to lie.
2. The disciple should avoid cursing or harming humans and other created beings (from bugs to Jinn) because avoiding to curse and harm is the character of the good and loyal friends of Allah. If a person is like this, then Allah protects him or her and their end will be good. They will reach to a high level in Allah's presence. Allah will protect them from being destroyed and protect them from harm. Allah rewards this person with being a blessing to human beings and close to Allah's essence.
3. The disciple has to keep his promise at all times unless he has a very good excuse. He must avoid not keeping his promise because not keeping a promise is in the same class as lying. As long as the servant of Allah tries to keep his/her promise the doors of generosity and blessings open to him/her. Loyal lovers of Allah love these people and they get a high station in Allah's presence. It is better that he avoids the habit of making promise, so that he may not be guilty of the breach of promise.
4. Even though a person has harmed or wronged him/her, the disciple should not pray for harm to come to him or curse him. Even if the mureed is wronged, he/she should not damn anyone, whether by word or action. The mureed should put up with this and be patient for Allah's sake. This virtue takes the owner to high stations in this world and the hereafter. Such a person will be loved by far and near ones.
5. The disciple should not blame other believers with attributing partners to Allah, with disbelief or cause trouble between people. This attitude is close to mercy and assists the mureed to reach high spiritual levels.
6. The disciple should not sin inwardly (in the heart) or outwardly. He/She should avoid eating things that are not halal and protect all the organs of his body from sin. This state is the best achievement in this world that a mureed can cultivate for the eternal life.
7. The disciple should earn his own livelihood and not be a burden to people who are independent of him/her. He should bear not only his own burden but also that of other people. Because of this virtue, the fear of Allah will make their worship complete and honorable.
8. The disciple /dervish must not or should not expect anything from people or desire what belongs to others. He should be unmindful of things which he needs, for to have no need is the mark of honour and the distinguishing trait of piety of the pious. The biggest honour and wealth and the highest level is to put one's whole trust in Allah only. Only with this attitude can the dervish be pious. Worship matures with this attitude. This is the state and action of one who give himself to Allah.
9. A disciple/dervish should not, either truly or falsely, intentionally or unintentionally, by mistake or on purpose take Allah's Name in vain or swear by the Name of Allah.
10. The disciple/dervish should take to hospitality and humility. With humility, the dervish reaches high levels of spirituality and stays at this high level. This is the base of goodness and the highest level of goodness. Because of this quality the lovers of Allah stay with him in troubled times. The Walis (Saints) visit him in the unseen and aid him in his difficulty. Humility is seeing everybody you meet as higher than you and thinking that they might be closer to Allah than yourself.
