The saying of Allah, exalted be His praise: "Not equal are those of the believers who sit (at home) without any disability and those who strive in the way of Allah with their wealth and their lives. Allah has preferred those who strive with their wealth and their lives over those who sit (at home) by a degree, and to each Allah has promised good." [Surah al-Nisa: 95]
