Indeed, those who have believed [in Prophet Muḥammad (ﷺ)] and those [before him (ﷺ)] who were Jews or Sabeans or Christians - those [among them] who believed in Allāh and the Last Day and did righteousness - no fear will there be concerning them, nor will they grieve.1
The believers in Muhammad, and the Jews, Sabians and Christians before Muhammad – whichever of them believes Allah and the Last Day and does good actions – they will have no fear for the future and will not be sad over that which they missed in the worldly life.
