The believer will have two rewards for his work on the Day of Resurrection: a reward insofar as he is a believer who acts according to the law, and a reward insofar as that work is an honorable act and that it is good. The Prophet, may God’s prayers and peace be upon him, said to Hakim ibn Hizam when he converted to Islam and he had done good in pre-Islamic times. I have converted to Islam as I mentioned above. Whoever is good, may God reward him for the good he did during his pre-Islamic era .
