הלכות תפילה ונשיאת כפים

Five things prevent one from praying, even though the time [for prayer] has arrived:1) the purification of one's hands;2) the covering of nakedness;3) the purity of the place of prayer;4) things that might bother and distract one; and5) the proper intention of one's heart.

The purification of one's hands - What does this imply? One must wash his hands in water until the joint. [Only] afterwards may he pray.[The following rules apply when] a person is travelling on the road when the time for prayer arrives: If he has no water, but is within four millin - i.e., 8000 cubits - of a source of water, he should proceed to it, wash his hands, and then pray. If the distance to the water is greater than this, he should clean his hands with pebbles, earth, or a beam, and pray.

When does this apply? [When the water is] ahead of him. However, if the place with water is behind him, we do not obligate him to retrace his steps more than one mil. However, if he has passed further beyond the water, he is not obligated to return. Rather, he should clean his hands and pray.When do the above statements requiring one to purify merely his hands alone for prayer apply? To the other services, but not for the Morning Prayer. For the Morning Prayer, one should wash his face, hands, and feet, and only afterwards, may he pray. If he is far from water, he may clean his hands only and then pray.

All the ritually impure need only wash their hands in order to pray, just like those not in such a state. Even if they are able to immerse themselves [in a mikveh] and ascend from their impure state, this immersion is not required [for prayer].We have already explained that Ezra decreed that only one who has had a seminal emission is prohibited from Torah study until he has immersed himself. The Rabbinical Court [that existed afterwards] decreed that [this applies] even to prayer, i.e., such a person alone should not pray until he immerses himself.These decrees were not put into effect because of questions of ritual purity and impurity, but rather to ensure that the Torah scholars would not overindulge in marital intimacy with their wives. Therefore, they instituted ritual immersion only for one who has a seminal emission, thereby excepting him from the other ritually impure.

Therefore, at the time of this decree, it was said that even a זב who had a seminal emission, a menstruating woman who emitted semen, and a woman who saw traces of menstrual blood after relations, required immersion to recite the Shema and to pray because of the seminal emission, despite [the fact that they remained] ritually impure.This is reasonable, since this immersion was not a matter of purity, but a result of the decree so that they would not constantly be with their wives.This decree regarding prayer was also abolished, since it was not universally accepted by the Jewish people, and the community at large was unable to observe it.

It is widespread custom in Shin'ar and Spain that one who has had a seminal emission does not pray until he has washed his whole body in water, [based on the command]: "Prepare to meet your God, Israel" (Amos 4:12 .To whom does this refer? To a healthy person or to a sick person who engaged in intimacy, but a sick person who has had an accidental emission is exempt from bathing and there is no such custom regarding this matter. Similarly, there is no such custom regarding a זב who has a seminal emission and a menstruating woman who emits semen. Rather, they should clean themselves, wash their hands, and pray.

The proper covering of one's nakedness: What is implied?Even if one covers his genitalia in the fashion necessary for the recital of the Shema, he may not pray until he covers his heart. If one did not - or was unable to - cover his heart, as long as he covered his nakedness when he prayed, he has fulfilled his obligation. However, a priori, he should not do so.

The purity of the place of prayer: What is implied?One should not pray in a place of filth, a bathhouse, a latrine or garbage heap. [Similarly, one should not pray] in a place that is not presumed to be clean until he checks it.The general rule is that one should not pray in any place in which one would not recite the Shema. [Thus,] just as one separates oneself from excreta, urine, a foul odor, a corpse and the sight of nakedness for Kri'at Shema, so too, he should separate himself for Shemoneh Esreh.

[The following rules apply] when one finds excreta in his place [of prayer.] Since he transgressed by not checking the place before he began to pray, he must pray again in a clean place.[The following rules apply] when one finds excreta while he is in the midst of prayer: If he can walk forwards such that [the feces] will be left four cubits behind him, he should do so. If not, he should move to the side. If he is unable [to do the latter], he should stop praying.The great Sages would refrain from praying in a house in which there was beer or brine at the time of its foaming because of the foul odor, even though it was a clean place.

Things that might bother and distract him: What is implied?One who must relieve himself should not pray. Whenever anyone who must relieve himself prays, his prayer is an abomination and he must pray again after he relieves himself.If a person can restrain himself for the length of time that it takes to walk a parsah, his prayer is considered prayer.Nevertheless, a priori, one should not pray until he has checked himself very well, checked his intestines, rid himself of phlegm and mucus and any [other] bothersome thing. [Only] afterwards should he pray.

[The following rules apply to] one who burps, yawns, or sneezes during prayer: Should a person do so voluntarily, it is deprecating. [However,] if the person checked himself before he prayed and did so against his will, it is of no consequence.If saliva comes up during prayer, one should cause it to be absorbed into his tallit or clothes. If he is bothered by this, he may throw it behind him with his hand in order that he not be bothered during his prayer and be distracted.If one passes gas unwittingly during prayer, he should wait until the gas subsides and return to his prayer.

One who desires to pass gas from below and is bothered exceedingly, to the extent that he cannot restrain himself, should walk back four cubits, [expel the gas], and then wait until the gas subsides. He should say:Master of all the world, You created us with many orifices and ducts. Our shame and disgrace is apparent and known before You. Shame and disgrace during our life, worm-eaten and decaying in our death.He then returns to his place and prays.
