[3:195] And their Lord answers them, 'I do not let the labor of any laborer among you go to waste, be you male or female - the one of you is as the other: and those who emigrated, and were expelled from their habitations, those who suffered hurt in My way, and fought, and were slain - them I shall surely absolve of their evil deeds, and I shall admit them to Gardens underneath which river flow'. A reward from God! And God - with Him is the fairest reward.
How can He not respond to them when He is the One who prompts them to call [on Him] and He is the One who is responsible for answering them. His promise of a beautiful reward for the call increases according to what they ask for from their needs.
Those who emigrated: leaving their familiar places and things.
Those who suffered hurt in My way: they were abused by poverty and blame and subjected to all kinds of trials and pains.
And fought, and were slain: they tasted different stages, the sweet and the bitter.
Them I shall surely absolve of their evil deeds: it means We will give them more than what they hoped for and more that what their acts and states merit.
