Wife should be pious

 Sefer Chasidim (1015) A pious person should pray that G-d provide him a pious wife and he should not be concerned with her wealth but only her piety. That is because wealth comes from good deeds. Therefore if he marries for wealth he will eventually lose it and only benefit from it in this World, while if he marries a good person he will become wealthy but the principal reward is in the future World
