"It is He who sends blessings upon you, and His angels [ask Him to bless you]" (Al-Ahzab: 43). The interpretation of Ibn Abbas: He said, the blessing of Allah is mercy, and the blessing of the angels is seeking forgiveness. "That He may bring you out from darkness into the light" (Al-Ahzab: 43), meaning: from misguidance to guidance.
Surah Al-Ahzab, from verses 44 to 48.
