“And listen for the day when the crier will call from a place quite near. The day when they shall hear the cry in truth. That is the day of coming forth”
Imam Sadiq (as) said, “The crier”will call out the name of the Qaem (as) and his father. “Truth” in the verse, “The day when they shall hear the cry in truth” refers to the name of the Qaem (as), which will be called out from the heavens on the day of the rising. (Tafseer Al Qummi volume 2 page 327)
