It is narrated from Hazrat Hudhaifah bin Yaman (may Allah be pleased with him) that your Noble Prophet (peace and blessings be upon him) said: Every good deed is charity. And among the things that people received from the first command of Prophethood is also this: When you do not feel shame, then do whatever you wish.
