The Book of Miscellany
Abu Hurairah (May Allah be pleased with him) reported:
The Prophet (ﷺ) said, "The upper hand is better than the lower one (i.e., the spending hand is better than the receiving hand); and begin (charity) with those who are under your care; and the best charity is that which given out of surplus; and he who asks (Allah) to help him abstain from the unlawful and the forbidden, Allah will fulfill his wish; and he who seeks self-sufficiency will be made self-sufficient by Allah".

[Al-Bukhari].

وعنه عن النبي صلى الله عليه وسلم قال‏:‏ ‏ "‏ اليد العليا خير من اليد السفلى وابدأ بمن تعول، وخير الصدقة ما كان عن ظهر غنًى، ومن يستعفف، يعفه الله، ومن يستغن، يغنه الله‏"‏ ‏(‏‏(‏رواه البخاري‏)‏‏)‏‏.‏
