His saying, "Not equal are those believers who sit at home, other than those with disabilities, and the mujahideen who strive in the cause of Allah with their wealth and their lives. Allah has preferred the mujahideen who strive with their wealth and their lives over those who sit by a degree, and to all Allah has promised the best reward, and Allah has preferred the mujahideen over those who sit with a great reward"
