O you who have believed, respond to Allāh and to the Messenger when he calls you to that which gives you life. And know that Allāh intervenes between a man and his heart and that to Him you will be gathered.
Respond to Allah and the Messenger when He calls you to what gives you life.
Every Muslim has to give charity. They asked: O Prophet of Allah, what of someone who has nothing? He said: He works with his hands, benefits himself and gives charity. They asked: And if he cannot? He said: He helps someone in need who calls for help. They asked: And if he cannot? He said: Then let him do good and hold back from evil, for that is charity for him.
