Muslims' participation with non-Muslims in collecting a sum of money to hold a party to see off non-Muslims is a kind of respect and honor to them which is not permissible for a Muslim to do or even take part in. It is obligatory to call non-Muslims to Islam, illustrate its beauty and draw it near to them perhaps Allah will guide them. (Part No. 1; Page No. 442) May Allah grant us success. May peace and blessings be upon our Prophet Muhammad, his family, and Companions.
