When a pious person died they make a place of worship at his grave

Re: When a pious person died they make a place of worship at his grave

The Souls Never Die - Sunni Islam
Death is separation of body and soul - Sunni Islam
We can not make the dead Hear, Allah Subhanahu wa Ta’ala can, So if you speak to passed away people it is in a state which brings together many aspects of Islam. That is why our Manners around Graves are very respectful, and we give Salam to the Muslim inhabitants of Graves. And pray Quran for them, and settle them in The Grave, and then they are questioned [the souls are questioned], and even after we avoid anything which causes them discomfort

Shias generally followed Sunnis, but they may word things differently and attribute everything to Imams, and Sunni Islam does not support Shias at All
