Those of the Muslims who (shirking fight) stay back (home) without any stressful condition (excuse), and those who fight in the cause of Allah with their material as well as human resources cannot be equal (in their reward and grading). Allah has exalted in rank those who fight in the cause of Allah with their material as well as human resources above those who stay back withdrawn. Allah has (surely) promised good to all (the believers, yet) He has bestowed the merit of excellence with a mighty reward (and bounty) to those who strive hard over those who stay behind.
