The Messenger of Allah (ﷺ) said, "Beware of newly invented matters, for EVERY invented matter is an innovation and EVERY innovation is a going astray, and EVERY going astray is in Hell-fire.” [Abu Dawud & At-Tirmidhi] On the basis of this, isn't everything the Shia does newly invented? Like bloodletting on ashura, cursing sahabas, shouting 'labaik ya hussain' and calling yourself the servant of Hussain, we are all the servant of Allah only. Not anyone else. Can you clarify a bit pls. Thanks!
