SECTION 44 The Prohibition against Sleeping while Wearing Tefillin. (1–2)

סימן מד אִיסּוּר שֵׁנָה בִּתְפִלִּין, וּבוֹ ב סְעִיפִים:

1 As long as one [is wearing] tefillin on his head or arm, he is forbidden to sleep in them,1 even briefly, for it is disrespectful to the tefillin to sleep while wearing them when they are uncovered. If one covers them with a cloth and his wife is not together with him, he may take a nap, but may not sleep for an extended period, lest he vent wind while wearing them.2

What should he do [as a precaution] that he not fall into a deep sleep and sleep for a lengthy period? He should nap while sitting, with his head between his knees.

[It is forbidden to divert one’s attention from tefillin while wearing them, but] sleep is not considered a diversion of attention. [Examples of] diversion of attention [from tefillin] are frivolity or levity (or excessive preoccupation with one’s material concerns),3 as stated in sec. 28[:1]. While sleeping, however, one forgets all the vanities of this world. [Nevertheless,] when his wife is together with him in bed, he should not sleep at all while [wearing tefillin], lest he forget them and engage in relations.

If one is not [wearing tefillin] on his head and arm but has them tied around his hand,4 he may sleep while [holding them], even for an extended period. There are, [however,] authorities who forbid sleeping for an extended period near tefillin even if they are placed on a table, unless one covers them with a cloth. This is a precautionary decree, lest one vent wind [in their presence].

The halachah follows the first approach, for [the Sages] were concerned with venting wind only when one is wearing [the tefillin], for [tefillin] require bodily purity.5

If one holds [tefillin] in his hand but they are not tied around it, he may not take even a brief nap [while holding] them, lest they fall from his hand.

When does the above apply? When one holds them without their container. If, however, they are in their container, according to all opinions one may sleep for even an extended period, for there is not as serious a concern if they fall.6 And even according to the latter opinion mentioned above, [if they are in their container] there is no need at all to be concerned about venting wind.

2 It is customary to fast if tefillin fall from one’s hand7 to the ground when they are not in their container,8 and similarly, [to fast] if a Torah scroll falls,9 even when it is in its encasement.
