Not equal are those of the believers who (when not all believers are required to mobilize for God’s cause) sit still without justifiable excuse (and without doing any harm to God’s cause) and those who strive (and fight) in God’s cause with their wealth and their persons. God has exalted in rank those who strive with their wealth and their persons over those who sit still. To each God has promised the best reward (Paradise), and yet God has exalted those who strive over those who sit still by a tremendous reward.
