And remember the favor of Allah on you and His covenant with which He bound you firmly, when you said: We have heard and we obey, and be careful of (your duty to) Allah, surely Allah knows what is in the breasts.

And those who made their abode in the city and in the faith before them love those who have fled to them, and do not find in their hearts a need of what they are given, and prefer (them) before themselves though poverty may afflict them, and whoever is preserved from the niggardliness of his soul, these it is that are the successful ones.
