The scholars unanimously agreed that what is obligatory in Wudu is to wash each part once, although washing each part two or three times is recommended. However, persisting in washing each part only once deprives the person of more reward.

The an`am animals are camels, cattle and sheep. No zakah is due on any other animals unless they are for trade. The nisab of camels is five. The nisab for cattle is thirty. The nisab for sheep is forty.
