Have they not travelled in the earth and seen how was the end of those who were before them? Mightier than these were they in strength-- and in fortifications in the land, but Allah destroyed them for their sins; and there was not for them any defender against Allah.

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.
