Additionally, there are differences in hadiths regarding the day of the uprising of the Mahdi. Nawroz and Ashura both are considered to be specified for the day of the uprising. According to Ja'far al-Sadiq, the Mahdi will appear on a Friday. His father, Muhammad al-Baqir, also emphasized on the day of Ashura being the day of the uprising, and that his reappearance will be announced from the heavens, after which the Mahdi will lean against the wall of the Kaaba, and invite the people towards truth. Muhammad al-Baqir narrated that Mahdi would appear after the night prayers, and that he would possess a banner and shirt of Mohammed with him.
