هُوَ الَّذِي يُصَلِّي عَلَيْكُمْ وَمَلَائِكَتُهُ (He is such that He and His angels send blessings to you. Al-Ahzab 33:43 ⧉) It means that when you have become used to dhikrullah in abundance and have become regular in recounting the perfections of Allah morning and evening, Allah would honor you and respect you by bestowing His Blessings and by the angels supplicating for you.
The word 'Salah' has been used in this verse Al-Ahzab 33:43 ⧉ for Allah Ta’ ala as well as for the angels but the applicable meaning are different. For Allah it means His bestowing blessings, and for angels who have no volition on their own, it means their supplication to Allah to bestow His blessings.
