Translation of the verse 36 from Surah Ar-Ra‘d : Number of verses 43 - - page 254 - Part 13.
Those to whom We have given the Book (such as 'Abdullah bin Salam and other Jews who embraced Islam), rejoice at what has been revealed unto you (i.e. the Quran), but there are among the Confederates (from the Jews and pagans) those who reject a part thereof. Say (O Muhammad SAW): "I am commanded only to worship Allah (Alone) and not to join partners with Him. To Him (Alone) I call and to Him is my return."
And [the believers among] those to whom We have given the [previous] Scripture rejoice at what has been revealed to you, [O Muhammad], but among the [opposing] factions are those who deny part of it. Say, "I have only been commanded to worship Allah and not associate [anything] with Him. To Him I invite, and to Him is my return."
(13:36) O Prophet ! some of those people whom We gave the Book before you rejoice in the Book We have sent down to you while there are others among the different sections who reject some of the things contained in this. Tell them plainly "I have been commanded to worship Allah alone and prohibited from setting up a partner with him. Therefore I invite you to Him and myself turn to Him. " *55
*55) This is in reply to a specific objection which was then raised by the disbelievers. They would say, "If he has brought the same Message that was brought by the Messengers before him (as he claims). why don't the Jews and the Christians who are the followers of the former Prophets come forward and welcome it?" The verse answers the objection and says that the taste followers of the former Prophets really rejoice in the Message of the Qur'an, but the false ones have been offended at it. Then it asks the Holy Prophet not to worry at aII about this, saying, "O Prophet, you should not mind at alI whether they are pleased or offended at it. Tell them plainly that this is the Guidance I have received from my Lord and I will follow it at alI costs."
