תפלת השחר עד חצות – Since the morning daily offering is offered until noon, according to the Rabbis, and according to Rabbi Yehuda, is not offered other than up until the fourth hour of the day. “Until the fourth hour” is until the end of the fourth hour which is one-third of the day at the time when the day has twelve [equivalent] hours, and so is its time is forever, until the end of the first third of the day, according to the length or shortness of their daytimes, as we have written above regarding the [recitation of the] Shema. And the Halakha follows Rabbi Yehuda.

תפלת המנחה עד הערב – until it gets dark.

עד פלג המנחה – the time of the “small Minha” which is from nine-and one-half hours [into the day] until the nighttime, which is [the equivalent of] two-and-one-half hours. Hence it is found that “Plag HaMinha” is one half of this measure which is one and one-quarter hours, and that the determined law/practice [in this matter] is that he who followed [the Sages] followed them, and he who followed [Rabbi Yehuda] followed him, and he who wants to follow the words of the Sages and recite the afternoon prayer until the evening should do so, as long as he does not recite the evening prayer at that time, since he considers that daytime period for the matter of reciting the afternoon service, he is not able to consider it nighttime and to recite] the evening service. But, if he comes to act according to the words of Rabbi Yehuda, that he should not recite the afternoon service other than until “Plag HaMinha” (i.e., 4:45 pm), which is an [halakhic] hour-and-a-quarter before the nighttime, he should do so, and from that point onwards, he may recite the evening service.

אין לה קבע – Its time [the evening service] is all night long, but when it [the Mishnah] teaches, “Ein Lah K’vah/It has no fixed time,” and it doesn’t teach, “its time is all night long” – it comes to teach us that the evening service is optional, since it was [considered] parallel to the offering of the limbs and fats which are offered all night, and these are optional, since when the blood is poured, the sacrifice is accepted, even though the limbs and fats were defiled or lost. However, nowadays, it (the recitation of the evening service), has been accepted as obligatory.

ושל מוספין כל היום – But if he recited [Musaf] later after the seventh hour, he has fulfilled his religious obligation, but he is called a sinner, and this is the Halakha.

מה מקום – that is to say, what is its nature?

שלא תארע תקלה – that no stumbling block should come through me, as it is explained in the Baraitha: “that I should not stumble in a matter of Halakha and that my colleagues would rejoice [in my being in error],” that evil should come upon me in that I caused them to be punished [through my errant decision].

אני נותן הודיה על חלקי – I express thanks for the good that has been my portion that my I have been placed among those who sit in the House of Study. And these two prayers [recited] when one enters the House of Study and when one leaves it are obligatory upon each and every person to recite them and so we say in the Baraitha – When he enters: What should he say? And when leaves, what should he say? – implying that it is obligatory to recite them [both].

מעין שמונה עשרה – There are those explain in the Gemara that a person recites a shortened form of each of the middle blessings in the Amidah and recites the concluding blessing for each one. And there are those who say [the prayer] “הביננו – O Lord our God, Cause Us to Understand [and to] Know Your Ways” which is one blessing which has an abstract of each of the middle blessings of the Shemoneh Esreh and we conclude this with the blessing, “Praised are You, who hearkens to prayer.”

שגורה בפיו – learned and fluent in it. And the Halakha is like Rabbi Akiva – for an individual whose prayer is not fluent in his mouth or is in a hurry , should recite the first three blessings [of the Amidah] and the last three blessings [of the Amidah] and the “הביננו” prayer in the middle , which is an abstract of all the middle [blessings], except for [the Amidah] during the rainy season since a person should not recite הביננו"” because he must mention the “request for rain” [“ותן טל ומטר לטובה – provide dew and rain for a blessing”] in the “blessing of the years” and also except for Saturday evenings and the conclusion of holy days where he needs to recite the Havdalah prayer in the [fourth] blessing, "חונן הדעת" – who grants knowledge.”

העושה תפלתו קבע – That his prayer appears to him like a burden, and the word “קבע/fixed” implies that it is like a fixed statute upon me to pray and I have to fulfill it.

מתפלל תפלה קצרה – And what is this short prayer? That he recites: “Save O LORD, your people…”

בכל פרשת העבור – Even at the time when they are turning aside to sin, “may their needs be revealed before You to have compassion upon them.” “פרשת”/crossroads – means “turning aside.” “העיבור”- of the crossroads. But the Halakha does not follow Rabbi Yehoshua, but rather, the prayer that is recited in a place of danger is “The needs of your people are many, etc.” And when a person recites it as he is walking, he does not recite the first three or last blessings [of the Amidah] but when he passes through the place of danger and is able to compose himself at ease, he must go back and recite the Amidah as it has been established if the time for its being recited has not yet passed.

היה רוכב על החמור ירד – The Halakha does not follow the [opinion of this] anonymous Mishnah but rather whether or not he has someone who can hold his donkey or not, he should not descend [from it] because his mind is not at ease when he descends [from it].

יחזיר את פניו – [He should turn his face] towards Jerusalem, as it says (I Kings 8:48), “and they pray to You in the direction of their land…”

יכוין את בלו כנגד בית קדשי הקדשים – as it states (I Kings 8:35), “and then they pray towards this place…”

באסדא – much wood tied and fastened together on which they float them on the river and people walk upon them, and in the language of the Bible (II Chronicles 2:15), they are called “rafts.”

אין תפלת המוספים אלא בחבר עיר – In communities of the city, that is to say, as a tzibbur/congregation and not as an individual.

בחבר עיר ושלא בחבר עיר – whether as a congregation or as an individual.

ר' יהודה אומר משמו – in the name of Rabbi Eleazar ben Azariah. There is a difference between the first teacher [of our Mishnah] and Rabbi Yehuda: An individual who dwells in a city where there aren’t ten [individuals – for a Minyan], according to the First Teacher [of our Mishnah] according to the opinion of Rabbi Eleazar who said, that they did not establish this other than with a community of the city, then an individual is exempt. But according to Rabbi Yehuda, an individual is only exempt when he is in a place where ten [individuals are found] and the שליח ציבור/emissary of the congregation exempts him. And the Halakha follows the Sages.
