It is very important for us to note the fact that a lot of people are ignorant of the various class of shirk as mentioned by the Prophet صلى الله عليه وسلم variety of hadiths. Due to this ignorance, they visit graves of their heroes and do all sort of things that are not permissible in the shari’ah. Some people direct their requests to the occupants of the graves who can’t even hear them, talkmore of providing what they need for them. This is as a result of exaggeration in loving human beings beyond limitation and burial of those people in conspicuous parts of their houses and masaajid. Allaah says about grave worshippers:
And those whom you invoke other than Him do not possess [as much as] the membrane of a date seed. If you invoke them, they do not hear your supplication; and if they heard, they would not respond to you. And on the Day of Resurrection they will deny your association. And none can inform you like [one] Acquainted [with all matters]. [Surat Fatir, Q35: 13- 14]
