The Repentance - 9:100
Allah is pleased with the pioneers of the emigrants (Muhajireen) and the helpers (Ansar) and those who followed them well, and they are pleased with Him. He has prepared for them Gardens in which rivers flow and where they will abide forever. This is the great victory.
The believers consider what they spend as a means to draw nearer to Allah:
The Banishment/59:8
Give first to the poor of the refugees who have been driven from their homes and their property because they sought the favor of Allah and His pleasure and supported Allah and His messenger. These are the righteous.
The Banishment/59:9
Those who had a home and a faith before them love those who emigrated to them and do not feel bitterness in their hearts because of what they have given. Even if they themselves are in need, they put them before themselves. Indeed, those who are protected from the selfishness of their souls are the saved.
The Cow/2:218
Those who believe and migrate and strive in the Way of Allah hope for the Mercy of Allah. Allah is Forgiving, Merciful.
The Spoils of War/8:72
Those who believe and migrate in the Way of Allah and strive hard with their wealth and their lives and those who shelter them and help them are friends of one another. Those who believe but do not emigrate with you, you are not responsible for them until they emigrate. But if they ask you for help on account of their religion, you should help them, provided it is not against a people with whom you have an agreement. Allah is All-Seeing of what you do.
The Spoils of War/8:73
And those who disbelieve are friends of one another. If you do not implement these commandments, there will be chaos and great mischief in the earth.
The Spoils of War/8:74
Those who believe, those who emigrate and strive in the Way of Allah and those who shelter and help them, these are the true believers. For them is forgiveness and abundant provision.
The Repentance/9:20
For those who believe and emigrate and strive in the Way of Allah with their money and their lives, there is a higher degree with Allah. They are the winners.
