Sahih Bukhari
Obligatory Charity Tax (Zakat)
Volume: 002 / Book Number: 024 / Hadith Number: 508
Narrated Hakim bin Hizam
The Prophet said, "The upper hand is better than the lower hand (i.e. he who gives in charity is better than him who takes it). One should start giving first to his dependents. And the best object of charity is that which is given by a wealthy person (from the money which is left after his expenses). And whoever abstains from asking others for some financial help, Allah will give him and save him from asking others, Allah will make him self-sufficient."
