What becomes obligatory for a Muslim before end of fasting in the month of Ramadhaan? Any obligation apart from fasting itself?

Question

Paying Zakaatul-Fitr is obligatory upon a Muslim who has the food or provision to sustain himself and those whom he is obliged to support on the eve and Day of Eid, provided that this exceeds hid basic needs. This Zakaah is given or collected and given to the poorest of the poor so that they may also enjoy the festivities on Eid-ul-Fitr.
