According to narrations, the murder of Nafs-e-Zakiyyah is one of the certain signs of reappearance of Muhammad al-Mahdi.[1] The hadith of Ja'far al-Sadiq mentions these signs: "there are five signs for our Dhuhur (the reappearance of the twelfth Imam), the appearance of Sufyani and Yamani, the loud cry in the sky, the martyr of Nafs-e-Zakiyyah,[1] and the earth swallowing (a group of people) in the land of Beyda."[6]
