Imam Ali (AS) said:

Beware, do not turn your face away from poor relatives, and do not withhold anything from them. Because keeping wealth will not add to it and losing it, will not create shortage. The one who holds back his giving hand from relatives, has taken away only one hand from them, but has taken away many hands from himself. And the one who spreads the wings of kindness, the friendship with his relatives will continue [1].
