Du`ah taking their expenses with them before traveling

Q 2: Some of the Du‘ah (callers to Islam), who travel around villages for Da‘wah (calling to Islam), have agreed to cover their own expenses when they go to the villages, instead of accepting the customary invitations extended from the villagers who used to provide them with food and slaughter a cow, a sheep, or more for them, at least every two days. They have done this knowing that not all villagers are able to afford this and some do not want to receive the Da‘wah. Is it Bid‘ah (innovation in religion) on the part of the Du‘ah to cover their own expenses, as some people claim?

A: Da‘wah to Allah (Glorified and Exalted be He) is one of the best deeds. (Part No. 12; Page No. 259) It is a good act on the part of the Du‘ah to support themselves with their own money, as this falls under the title of self-sufficiency and non-reliance on others. Therefore, there is nothing wrong with taking the expenses they need with them wherever they go.May Allah grant us success. May peace and blessings be upon our Prophet Muhammad, his family, and Companions.
