Question : This is a questioner for the program "Question by Phone." He says in this question: Is making a vow to the righteous awliya (close friends of Allah) forbidden or permissible? How can it be permissible? And how can it be forbidden? May Allah reward you with good.

Answer : Praise be to Allah, Lord of the worlds, and I send prayers and peace upon our Prophet Muhammad, and upon his family and his Companions, and upon those who follow them with excellence until the Day of Judgment. First, a vow (nadhr) is disliked (makruh), even if it is made for Allah the Mighty and Majestic, because the Prophet (peace and blessings be upon him) forbade vows and said that they do not bring any good, that they do not avert a decree. The decree of Allah is effective whether you make a vow or not, and the good that Allah has decreed for you will be realized whether you make a vow or not.
I am truly amazed at people who are afflicted with illnesses; instead of asking Allah for health, they resort to vows, saying, "If Allah grants me health, I have vowed to Allah that I will slaughter a camel, or fast for the rest of my life, or fast three days every month, or pray so much, or give so much in charity." All of this is prohibited because of the danger it poses and because it binds a person to something that Allah the Exalted has not made obligatory upon him. Many people make such vows. When the time comes, they become sluggish and slow, and they knock on the door of every scholar to try to get out of their vows. But they do not succeed. Then Satan makes it heavy for them to fulfill the vow, so they fall into what Allah the Exalted mentioned in Surat al-Tawbah, where He says: We will remind them that . This matter is serious; the matter of vows is very serious.
As for if it is a vow to the awliya (close friends of Allah), drawing near to them and honoring them with what is vowed, such as vowing to slaughter for a certain grave or for a certain wali (close friend of Allah), then this is major shirk (associating partners with Allah) that takes one out of the religion, because drawing near with acts of obedience is only to Allah the Mighty and Majestic. So whoever draws near to other than Allah the Exalted with worship, he is one who associates partners with Allah, and . But if he vows to slaughter for a scholar or a true worshipper if he is brought to him as an honor to him, in the sense of honoring a guest, then there is nothing wrong with it, because this vow of his is not drawing near to this person, but it is honoring him, and he is alive and present, coming to the person to honor him with this vow he made. Therefore, the person does not feel at that time that he is drawing near to this person, but feels that he is honoring him. As for vows to the dead, it is major shirk (associating partners with Allah) that takes one out of the religion. It is incumbent upon the one who does it to repent to Allah so that he is not forbidden from entering Paradise, for Allah the Exalted says: And upon the scholars of the Muslims in the lands where their common people do that, it is obligatory upon them to clarify this to them, and that it is shirk (associating partners with Allah) that takes one out of the religion, and to warn them against it, and to know that they are accountable for that before Allah the Mighty and Majestic, as He the Exalted said: So it is obligatory upon the people of knowledge to clarify the truth to people, whether they ask with the tongue of speech or ask with the tongue of circumstance. May Allah reward you with good, Honorable
