21. Al-Husayn ibn Muhammad has narrated from Mu‘alla ibn Muhammad from al-Washa’ from al-Muthanna al-Hannat from al-Qutayba al-A'sha from Ibn Abi Ya‘fur from a slave of Banu Shayban that Abu Ja‘far (al-Baqir) (as) said
"When our Qa’im (Imam al-Mahdi) rises, Allah will place His hand over the heads of His servants and He will place their intelligence together and complete their understanding.”
