Visiting Shrine Of Holy Person (Wali Ullah)
You did the right thing by praying for the person in the grave. The ones who are dead need our prayers and not the other way round. It is Allah alone who decides who is truly holy and who is not. We hope for the best and pray that Allah accepts the good deeds of every Muslim. Declaring someone a waliullah is not within our authority; only Allah can determine this. There is no reason to disrespect anyone regarded as special by another group of Muslims, as this only hurts their sentiments and serves no purpose. Instead, we should share the message of the Quran on this matter and leave the rest to Allah. Please watch the following videos to better understand the Islamic guidance on this topic.
