Hadith.1259 - Imam (as) said:
"Indeed, the close angels descend every Jumu’ah, carrying silver tablets and golden pens. They sit at the doors of the mosques on chairs made of light and write down the names of those who attend the Jumu’ah prayer—the first, the second, and the third—until the Imam comes out. When the Imam comes out, they roll up their scrolls."
