Question 18: I made a vow to offer a sacrificial animal to Shaykh `Abdul-Raheem Al-Qinawee, but a righteous friend of mine met me and told me that it is not permissible for me to do so, as such a practice is regarded as Shirk (associating others with Allaah in His Divinity or worship). Thus, I decided to do nothing until I receive a Fatwaa on this question from Your Eminence. It is worth mentioning that my sons sold the animal I made a vow to slaughter, but its price is still with me. We would be grateful if you could tell us whether offering sacrificial animals to such dead shaykhs is Haraam (prohibited) or not? If such a practice is prohibited, what should we do with regards to the vow? We would be grateful if you could send the reply as soon as possible.
Answer: It is prohibited to offer a sacrificial animal to the dead shaykh whose name is mentioned above or to other shaykhs, as offering sacrificial animals is an act of `Ibaadah (worship) through which a Muslim can get closer to their Lord and offering them to other than Allaah is regarded as major Shirk (associating others with Allaah in His Divinity or worship that takes the Muslim out of Islaam)... read more here.
