Calling a disbeliever to Islam in the workplace and accepting his gift

Question:
Honorable Shaykh, Sa'd says: We have a person at our workplace who is a Qadi, and we deal with him with good treatment and good character. If someone says to him, "I am a Muslim," he speaks ill of us, as one of our colleagues who is with us translated for us. Given what our Shaykh said, do we continue calling him to Islam? Or do we leave him off, knowing that we fear Allah and love him? And is it permissible to accept his gift?

Answer:
Yes, continue advising him, even if he gets angry; continue advising him, but with wisdom, good exhortation, and sound presentation. Continue with him, perhaps Allah will guide him. There is no harm in accepting a gift from a disbeliever; accepting a gift is not a problem. The Prophet (peace and blessings be upon him) accepted a gift from al-Muqawqis, the king of Egypt. Likewise, the Companions used to send gifts to their relatives who were disbelievers. So a gift between a Muslim and a disbeliever is not a problem. Yes.
