What is my position toward my father who died while believing in the awliya (close friends of Allah)?

Question:
May Allah reward you, Honorable Shaykh. This questioner says: My father died while believing in the awliya (close friends of Allah), or in the concept of awliya. He believed his Shaykh and carried out the specific recitations (awrad) that he was required to perform. They would gather for what they call "al-'ataqah," which is gathering for food after the recitations of their Shaykh. The question is: What must I do for him?

Answer:
If your father did not fall into any shirk (associating partners with Allah)—meaning he was safe from shirk and from calling upon anyone other than Allah the Exalted, and he died upon tawhid (the oneness of Allah)—then you should make du'a' (supplication) for him, seek forgiveness for him, give charity on his behalf, and perform Hajj on his behalf. The fact that he committed sins or engaged in some bid'ah (religious innovations) that are less than shirk does not prevent you from giving charity for him, seeking forgiveness for him, and making du'a' for him, because he died upon Islam. However, if he died upon the belief of shirk, worshipping the awliya (close friends of Allah) other than Allah, and calling upon graves, and did not repent from that, then he died upon shirk. You do not seek forgiveness for him, you do not make du'a' for him, and you do not give charity on his behalf. Allah the Exalted said: . Yes.
