When you select your spiritual guid and swear allegiance, you should faithfully act upon the following principles:-

Unless you develop inner vision or your spiritual guide does not permit, you should not visit any other saint for seeking instructions or gaining bounty. Act upon his orders and instructions and guidance faithfully. Sit in his company silent and guard your manners. Maintain perfect manner and discipline in all your actions and movements in his company keeping in mind that it does not reach the stage of idolatry, that is, you should not bow so low as it may resemble RUKU.

Besides disciples, even common people should observe these rules when ever they go to the assembly of any saint. Thay should never talk about mundane affairs in their company. They should not ask about invisible and unseen matters. This is the greatest disrespect to the vocation of a saint and his respectability. Such a vocation is not of the saints but of astrolgers, fortune-tellers, palmists etc. And it is prohibited to believe it. In Chapter An'am, Verse 50, while addressing the Prophet(SAW), Allah says:" Say:, I do not say to you, I have with me the treasures of Allah, nor do I know the unseen, nor do I say to you that I am an angel". When Allah says that even Prophet has no knowledge of unseen how do you expect and hope that saints will tell you your futur. You should also not go to saints will tell you your future. You should also not go to saints for amulet and charm. This is the work of charmers. Saints never resort to amulet and charm.

They only pray and supplicate. Go to them for supplication, of course. The proper way of doing it is that when you go to a saint, do not start narrating in detail story and previous history and tales as we lay bare before lawyers in law-suits and in illness to a doctor, but tell in brief that I want supplication for such thing. Remember that by listening to stories of long and lingering mundane affairs the attention of the saint is diverted from Allah and he feels disturbed. In this situation, spontaneous supplication with perfect attention will not be forthcoming. You should not do anything which makes the Sheikh sullen. If he is pleased with your word and develops exhilaration, supplication is also accepted in such a situation. If any saint promises that, God willing, you will achieve your objective, you should not remind him repeatedly for it.

Remember that he owes you nothing. There is no harm on occasion you just mention about it to him as humbly as you can. If you achieve your objective for which you had sought his supplication, it is your moral duty to inform him and thank Allah and the holyman. It is not permitted to repay as acknowledgement of gratitude and present in lieu of supplication. Of course gifts can be given occasionally because to take and give gifts are permitted according to the religious law. This leads to help develop affection and firm up connections and relationships.But take into your head that gifts are not given as remuneration. This should only be given as a token of love and affection. (for detail pls read book
