The Messenger of Allah (ص) said to Ali (ع):
"When the day of Resurrection comes, I will beseech Allah, and you will resort to me, and your children will call upon you, and your followers (Shias) will call upon them, and you will see to where they will lead us."
Zamakhshari, Asas al-Balagha, page 155; and similar to this, in Rabi al-Abrar, (Zamakhshari, V.2, p.159). It is recorded in the chapter concerning Goodness and righteousness and reliving good and peace. And in Nazm Durar al-Simtain, (Zarandi, page 243) the same has come down in a hadith where he recommended his Ummah to cling to his Ahl al-bayt and explained that his progeny would resort to their Prophet (on the Resurrection day).
