This is the fourth obligation in Umrat-ut-Tamatu'. In sa'y too, intention to seek nearness to Allah is obligatory but there is no obligation to cover the private parts, [although exposing one's genitals in a public place is not allowed], or for taharah from urine or excrement, although it is preferable (al awla) to be tahir during sa'y.

Rule 333: Sa'y is to be performed after tawaf and its prayer. If it is performed before the tawaf or prayer, it is obligatory to repeat it after performing both. As for the one who forgets to perform tawaf, but recalls after performing sa'y, the rule has already been set out.

Rule 335: Sa'y consists of seven laps. The first round starts at Safa and ends at Marwah. The second round is a reversal of the first, the third is like the first, and so on until the seventh round ends at Marwah. One should cover the whole distance between the two mounts in each round; there is no need to climb any of them, even though it is preferable and precautionary (awla and ahwat) to do so. As a matter of precaution, it is obligatory for performing sa'y to be continuous, i.e. there should not be a break between the rounds.
