Important Issue of Praying on Graves in Islam

It has been seen in many cases that people go to some pious person’s grave and start praying and asking them to fulfill their needs. Many extreme cases are seen on the famous shrines of the Sufi people who had devoted their whole life by living the life that Allah has commanded and by preaching the principles of Islam to other people. No doubt that the rank of those Holy saints can’t be compared to the common man but that does not mean that one start worshiping their graves and keep asking them to fulfill their needs. All needs of a man can only be fulfilled by Allah Almighty and these acts of worshiping the graves is the greatest sin of all which is considered as Shirk.
