It is said he gave victory to the religion of Allah after it had long been oppressed. He crushed stone by the mere sound of his voice. He is the conqueror of the Holy land. The successor of Moses who carried on his legacy was the mighty warrior Joshua ibn Nun.
According to the narrations, Joshua will return with the Qa’im:
From Mufaddal ibn Umar that Imam Al-Sadiq (pbuh) said: “The Qa’im (pbuh) will emerge from the back of Kufa with twenty-seven men, fifteen from the people of Moses (pbuh) who guided with the truth and with it made justice, and seven from the Companions of the Cave and Joshua ibn Nun, and Salman and Abu Dujana Al-Ansari and Miqdad and Malik Al-Ashtar, who will become Ansar (Supporters) and Rulers between the hands of the Qa’im (pbuh).”

– Mo’jam Ahadeeth Al-Imam Al-Mahdi, Ali Al-Korani, 1st ed., v.5, p.122, hadith 1543
Joshua has returned in this day and age to support the Qa’im, and is one of the planets of the Second Mahdi Aba Al-Sadiq (fhip).
