No water? Perform your ablution with plain, purifying earth that contains dust

N: When unable to use water, dry ablution is a dispensation to perform the prayer or similar act without lifting one's minor or major impurity, by the use of earth for one's ablution.)

e12.1 Three conditions must be met for the legal validity of performing dry ablution.

(a) The first is that it take place after the beginning of the prayer's time if it is for an obligatory or a nonobligatory one that has a particular time. The act of lifting earth to the face and arms (N: the first step of dry ablution) must take place during that time. If one performs dry ablution when unsure that the prayer's time has come, then one's dry ablution is invalid, even if it coincides with the correct time (dis e6.2(A:)). If one performs dry ablution in midmorning for the purpose of making up a missed obligatory prayer, but the time for noon prayer comes before one has made up the missed obligatory prayer, then one may pray it (N: the noon prayer) with that dry ablution (N: because one did not perform dry ablution for it before its time, but rather performed dry ablution for a different prayer in that prayer's time, which clarifies why this does not violate the conditions of praying with dry ablution), or one could pray a different missed prayer with it (O: as one is not required to specify which obligatory prayer the dry ablution is for).

(b) The second condition is that dry ablution must be performed with plain, purifying earth that contains dust, even the dust contained in sand; though not pure sand devoid of dust; nor earth mixed with the likes of flour; nor gypsum pottery shards (O: which are not termed earth), or earth that has been previously used, meaning that which is already on the limbs or has been dusted off them.

(c) The third condition is inability to use water. The person unable to use water performs dry ablution, which suffices in place of lifting all forms of ritual impurity permitting the person in a state of major ritual impurity (janaba) or woman after her menstrual period to do everything that the purificatory bath (ghusl) permits them to do. If either of them subsequently has a minor ritual impurity (hadath), then only the things prohibited on minor impurity are unlawful for them (def:e8.1) (N: not those prohibited on major impurity (e10.7), that is, until they can again obtain water to life their state of major impurity, when they must, for the dry ablution is only a dispensation to pray and so forth while in states of impurity and is nullified by finding water).
