יִֽירָא֥וּךָ עִם־שָׁ֑מֶשׁ וְלִפְנֵ֥י יָ֝רֵ֗חַ דּ֣וֹר דּוֹרִֽים׃
Katatakutan Ka nila habang may araw, at habang may buwan, sa lahat ng salinlahi.
Mishneh Torah, Reading the Shema
When is the right time for reading the Shema by day? To observe the precept properly, one should begin reading it before sunrise, so as to conclude the recital of the Blessing after the Shema exactly at sunrise. This interval is about a tenth of an hour before the Sun rises. One who deferred reading the Shema till the Sun had risen, has discharged his obligation—the period for reading the Shema being extended, for one who delayed, to the end of the first three hours of the day.
Kitzur Shulchan Arukh
The ideal time for praying the morning Amidah is at sunrise, as it is written: "So they will fear You when the sun shines."1Psalms 72:5. Nevertheless, if you prayed after day-break, your obligation is fulfilled. The time for prayer continues until the [first] third of the day,2The day is reckoned from sunrise to sunset. Daybreak is approximately an hour and twenty minutes before sunrise. and must not be delayed longer. Nevertheless, if it so happened that you delayed longer, even intentionally, you may pray till noon. Even though the reward is not the same as when you pray at the proper time, you will still be rewarded for praying. If you willfully delayed until noon without praying, you can no longer make up for it, and concerning such a person it is said: "What is crooked cannot be made straight."3Ecclesiastes 1:15. Cases where the delay was unintentional or because of circumstances beyond control, will be discussed in Chapter 21.
Shulchan Arukh, Orach Chayim
The Laws of Prayer [i.e. the Amidah] and its [Proper] Time, containing 8 s'ifim
The time for the morning Tefillah (i.e. Amidah): its commandment is that it should begin with the "blossoming" (i.e. rising) of the sun, as it is written, "They will revere You with the sun (Psalm 72:5)." And if one prayed from the [time of] "the pillar of the morning" (i.e. dawn) and the appearance of the east has become light, one has fulfilled [one's obligation]. And its time continues until the end of four hours which is a third of the daytime. And if one erred or transgressed and prayed after the fourth hour until noon, even though one does not have the [same] reward as praying at its [proper] time, in any case there is still a reward of prayer. Rem"a: And after noon it is forbidden to pray the Tefillah of the morning (Beit Yosef in the name of the Rashba [Rabbi Shlomo ben Adret], Chapter: "Morning Prayer") . And see below, the beginning of Siman 108].
