Those who said of their brethren whilst they (themselves) held back: Had they obeyed us, they would not have been killed. Say: Then avert death from yourselves if you speak the truth.

The holders back from among the believers, not having any injury, and those who strive hard in Allah's way with their property and their persons are not equal; Allah has made the strivers with their property and their persons to excel the holders back a (high) degree, and to each (class) Allah has promised good; and Allah shall grant to the strivers above the holders back a mighty reward:

Those who were left behind were glad on account of their sitting behind Allah's Messenger and they were averse from striving m Allah's way with their property and their persons, and said: Do not go forth in the heat. Say: The fire of hell is much severe in heat. Would that they understood (it).
