Translation of the verse 43 from Surah Al-Ahzab : Number of verses 73 - - page 423 - Part 22.
He it is Who sends Salat (His blessings) on you, and His angels too (ask Allah to bless and forgive you), that He may bring you out from darkness (of disbelief and polytheism) into light (of Belief and Islamic Monotheism). And He is Ever Most Merciful to the believers.
It is He who confers blessing upon you, and His angels [ask Him to do so] that He may bring you out from darknesses into the light. And ever is He, to the believers, Merciful.
(33:43) It is He Who lavishes His blessings on you and His angels invoke blessings on you that He may lead you out of darkness into light. He is Most Compassionate to the believers. *79
*79) This is meant to make the Muslims realize this: 'The jealousy and malice of the disbelievers and hypocrites towards you is only due to the mercy that Allah has shown you through His Messenger. It is through him that you have been blessed with the faith, that you have come out from the darkness of unbelief and ignorance into the light of Islam, that you have developed the high moral and social qualities by virtue of which you stand distinguished above others. It is this which has filled the jealous people with malice and rage against the Messenger of Allah. However, in this state you should not adopt any unbecoming attitude which might alienate you from the mercy of Allah." The word Salat when used with the preposition 'ala by Allah in respect of the servants, it means mercy and kindness and compassion and when used by the angels in respect of the human beings, it means the prayer for mercy. That is, the angels pray to Allah to bless the human beings with His bounty and favours. Another meaning of yusalli 'alaikum is: "Allah biasses you with renown among the people and exalts you to a high rank so that the people begin to praise you and the angels begin to eulogize you."
