Musannaf Ibn Abi Shayba 33:1488

Affan narrated to us, he said: Aban ibn Yazid al-Attar narrated to us, he said: Qatada narrated to us, that Abu al-Aliyah al-Riyahi narrated to him, from the hadith of Sahl ibn Hanzala al-Abshami, that he said: No people gather to remember Allah except that a caller from the sky calls out: "Rise, you have been forgiven; your evil deeds have been replaced with good deeds."
