History

How was Hazrat Bilal (Radiyallahu Anhu) tortured?

Q: I have read about how Hazrat Bilal (Radiyallahu Anhu) was tortured. I have read that he was tortured by:

  1. Made to lie on hot desert sand.
  2. Thrown into boiling water.
  3. Dragged through the streets with ropes. 

Are these three types of torture proven from authentic ahadith? What other ways do the Ahadith mention about how Hazrat Bilal (Radiyallhu Anhu) was tortured?

Taj Mahal

Q: We often hear the story behind the Taj Mahal. Is it true that it was built by a Wali of Allah as a Musjid and is there any Islamic significance behind it?
