Shaikh Ibn Baaz, may Allaah have mercy on him, said, “What is obligatory upon a Muslim is to fast out of faith and in the hope of receiving Allaah’s reward, not for showing off or to be heard or just to blindly follow the people or to follow his family or the people of his city, rather what is obligatory upon him is that the impetus for fasting be his faith that Allaah has made it obligatory upon him and [also] his hope for the reward that is with his Lord for doing so, and this applies to standing for prayer in Ramadaan [too], the Muslim should do it out of faith and hoping for Allaah’s reward from it, not for another reason.”
