Question: Assalam aleykum
I am planning to develop an android app. I am publishing it for free. So I wish to add a donate button so that anyone can donate money to me through PayPal if they wish to. Is it allowed to receive this money?
Answer: assalamu alaykum
This is perfectly permissible. It is established that the Prophet (blessings and peace be upon him) accepted gifts and the like from non-Muslims. [Bukhari]
