Zakat (Kitab Al-Zakat)
Dawud :: Book 9 : Hadith 1641
Narrated Abdullah ibn Mas'ud:
The Prophet (peace_be_upon_him) said: If one who is afflicted with poverty refers it to me, his poverty will not be brought to an end; but if one refers it to Allah, He will soon give him sufficiency, either by a speedy death or by a sufficiency which comes later.
