Those of the believers who sit (and do not go to war) other than those who have an excuse, are not equal with those who strive hard (and fight) in the Way of Allah with their wealth and lives; Allah has made the strivers with their property and their lives to excel over those who remain behind, by degrees, and Allah has promised “Husna” (the most excellent) to all; But Allah has preferred the Mujahideen over those who remain behind with a Mighty Reward (Wage).
(For the striving) there are degrees, forgiveness and mercy from Him; and Allah is Oft-Forgiving, Most Merciful (manifests with His Mercy attribute).
Surely those whom the angels cause to die who wrong their souls, they asked; in what (condition) were you? (They) said: “We were weak (powerless) in the Earth”. They (the angels) said: “Was not Allah’s earth spacious, so that you should have migrated therein”? For those, their destination is Hell - and evil it is as a destination.
Except for the weak (powerless) among men, women and children who cannot find a resolution nor be directed to a way (for emigration).
For those it is expected that Allah will pardon them, and Allah is Oft-Pardoning, Oft-Forgiving.
And whoever emigrates for the cause of Allah will find on the earth many spacious locations; and whoever goes forth from his house as an emigrant to Allah and His Messenger and then death overtakes him, his reward is indeed with Allah and Allah is Oft-Forgiving, Most Merciful.
And when you journey in the earth there is no sin on you if you shorten the prayer, if you fear that those who disbelieve will cause you harm; surely the disbelievers are an open enemy to you.
