Al-Husayn ibn Muhammad has narrated from Mu‘alla ibn Muhammad from al-Washsha’ from al-Muthanna al-Hannat from al-Qutayba al-A 'sha’ from ibn abu Ya‘fur from a slave of clan of Shayban from abu Ja‘far (a.s) who has said the following.
"When al-Qa’im, (the one who will rise with Divine Authority) the guardian, of our family will appear from occultation, Allah will place His hand over the heads of His servants and, thus, He place their intelligence together and complete their understanding."
