I am from India (Bombay) Al-Hamdu Lillaah, my father was from a very good and rich family, we are four brothers and two sisters. I don't know what was the problem but my father was getting lose his business and he was getting loss in any business he do, after some time my father lost all his business and our financial position become very poor even some times there was nothing to eat but we are surviving anyhow, then my father become very short temper and he get sick every year he get sick for four months and after he gets cure very well like before but in the next year he gets sick again this was continue for seven years, doctor check everything they can but no result they don’t find any cause or treatment for that later he died, at that time we were still teen, now its almost 14 years for my father die.
Allaah help us and we grow up and get married, my big brother is like my father very short temper abusing anyone and he is not doing any work, when my elder sister gets married their financial condition was very good but after marriage their financial condition is become very bad. When my younger sister gets married their financial condition was very good but after marriage some time their financial condition becomes very bad and some time very good. Then I get married Al-Hamdu Lillaah, I am getting good money every month (I am working in Saudi Arabia, Riyadh as a Controls Engineer) but after my marriage I can’t save any money I borrow money from others, then my younger brother get married he is also going through loses in his business and family problems one after one.
One of my friend in Riyadh he has good knowledge in Islam told me that someone close to your family had done “Amal” on your family (Black Magic or Sahir), I did not all this to my friend before but later I told him my complete story, he told me that “Amal” was done since your father was alive then later on you people, Amals affect will continue to your generations especially after marriage so better you consult good Aalim (Scholar) in India who can do Ruqyah for this otherwise you people will keep getting problems I told him I don’t want to do anything which is not allowed in Islam (i.e. Amulets) then he told me that everything is in Qur'an for now Pray two Raka'h then Recite [Surah Al-Takwir, No: 81] (Surah Faatihah in starting and end) for three days Inshaa Allaah will show you the way, and when you go to India go to your father's grave and ask to forgive us if we had done some misbehave with him talk to him like we talk to alive people. So I would like to ask you the correct way in according to Islam and Shariah. Please help me for Allaah’s sake.
Once again I am very thankful to you for giving time and reading my story May Almighty Allaah bless you and give reward in this life and hereafter and accept your prayers, I have one request please do not put this detail on Internet keep it with you I will appreciate for that and send me reply as soon as possible.

All perfect praise be to Allaah, The Lord of the Worlds. I testify that there is none worthy of worship except Allaah, and that Muhammad is His slave and Messenger. We ask Allaah to exalt his mention as well as that of his family and all his companions.

You have to know that what has befallen you is a kind of affliction and trial and that has been predestined by Allaah who afflicts his servants so that a patient person will be distinguished from others. However, a believer has to patient about the hardship that befalls him and be pleased with whatever is predestined for him in order to console himself from the tribulation. The Prophet said: "The greatness of the reward stems from the greatness of the affliction; if Allaah loves a people, He tries them. So, whoever is pleased (with such distress and calamity) will get the reward of being content and whoever is angry and dissatisfied, will get the punishment of being discontent." [At-Tirmithi]

It might be that what had befallen you is because of a sin that you had committed or due to your negligence in being grateful to Allaah for the bounties and blessings that He has given you. Allaah says (which means): {And whatever of misfortune befalls you, it is because of what your hands have earned. And He pardons much.}[42: 30]. So you have to take the initiative to repent sincerely and seek forgiveness from every sin. You have to be thankful to Allaah about what had befallen you, as this is at the same time a warning and admonition to you as well as a way to eradicate your sins. It might also be that the calamity that struck you is due to magic or the like, so if you are sure that it is magic then seek the legislated Ruqyah (to have some Qur'aanic verses and Prophetic supplications read on you). As regards amulets which contain Qur'an, then that is a controversial matter among the scholars. Our opinion here in Islamweb is that they are not permissible because of saying of the Prophet : "Incantations, amulets and bewitchment (in order to make the husband increase his love towards his wife) are Shirk." [Abu Daawood] Finally, we remind you that it is not permissible to accuse a specific person or a given family of having done magic to you without evidence.

As regards the advice of your friend to go and visit the grave of your father to ask forgiveness from him, this is something that has no foundation in religion. On the contrary, you should supplicate as much as possible to Allaah to forgive him if he is a Muslim, especially if you were negligent in his regard, and repent from being negligent and undutiful to him.

Allaah knows best.
