Iran has officially announced the funeral schedule for late Supreme Leader Ayatollah Ali Khamenei, months after his death in a joint US-Israel strike. The funeral ceremonies will begin in Tehran on July 4 and continue through multiple cities before culminating in his burial in Mashhad on July 9. Millions are expected to participate in what could become one of the largest public mourning events in Iran's modern history. 

Shia Muslims commemorate the martyrdom of Imam Hussain ibn Ali, the grandson of Prophet Muhammad. The community members wear black clothes, organise Majlis and take out processions during Muharram. And know why during Muharram and Safar (the next month of Islamic calendar), Shia Muslims refrain from attending and celebrating joyous events.
