مختصر صحيح بخاري
Mukhtasar Sahih Bukhari
Reciting aloud in Fajr prayer.
Narrated Ibn Abbas (may Allah be pleased with them) that the Prophet (peace and blessings of Allah be upon him) recited aloud in those prayers in which he was commanded to do so, and remained silent in those in which he was commanded to do so. And "Your Lord is not forgetful" (that He would give a wrong command by mistake. Surah Maryam: 64). "Indeed, for you in the Messenger of Allah (the actions and sayings) is a good example." (Surah Al-Ahzab: 21).
Reciting two surahs in one rak‘ah, or out of order, or only part of a surah.
It is narrated from Sayyiduna Ibn Mas'ud (may Allah be pleased with him) that a man came to him and said: "I recited a Mufassal surah in one rak'ah at night," and he said, "I recited it as quickly as poetry is recited." Indeed, I know those similar surahs which the Prophet (peace and blessings of Allah be upon him) used to recite together, then he mentioned twenty Mufassal surahs (that from these) the Messenger of Allah (peace and blessings of Allah be upon him) used to recite two surahs in each rak'ah.
Only Al-Fatiha is recited in the last two rak‘ahs.
It is narrated from Sayyiduna Abu Qatadah (may Allah be pleased with him) that the Noble Prophet (peace and blessings of Allah be upon him) used to recite Surah Al-Fatihah and two other surahs in the first two rak'ahs of Zuhr, and in the last two rak'ahs (only) Umm al-Kitab (i.e., Surah Al-Fatihah). And sometimes he would make us hear a verse, and he would prolong the first rak'ah more than the second, and the same was the case in Asr and likewise in Fajr.
Imam saying Ameen aloud.
Narrated from Sayyiduna Abu Huraira (may Allah be pleased with him) that the Messenger of Allah (peace and blessings of Allah be upon him) said: "When the Imam says Ameen, you should also say Ameen, because whoever's Ameen coincides with the Ameen of the angels, his previous sins will be forgiven."
Virtue of saying Ameen.
Narrated from Sayyiduna Abu Huraira (may Allah be pleased with him) that the Messenger of Allah (peace and blessings of Allah be upon him) said: "When any one of you says Ameen and the angels in the heavens say (Ameen), and these two coincide with each other, then his previous sins are forgiven."
Bowing behind the row—what is the ruling?
Narrated from Sayyiduna Abu Bakr (may Allah be pleased with him) that he reached the Prophet (peace and blessings of Allah be upon him) while he was in the state of bowing (ruku‘), so before joining the row, he performed ruku‘. He mentioned this to the Prophet (peace and blessings of Allah be upon him), so he (peace and blessings of Allah be upon him) said: "May Allah increase your eagerness (for good deeds), but do not do this again."
Completing Takbir upon reaching bowing.
‘Sayyiduna Imran bin Husain (may Allah be pleased with him) says that he performed prayer with the Commander of the Faithful, Ali (may Allah be pleased with him), in Basra, so the Commander of the Faithful, Ali (may Allah be pleased with him), reminded us of the prayer which we used to perform with the Messenger of Allah (peace and blessings of Allah be upon him). Then (Sayyiduna Imran, may Allah be pleased with him) said that when he would stand up and when he would bow down, he would say the takbir (that is, Allahu Akbar).
Saying Takbir when standing after prostration.
Narrated from Sayyiduna Abu Huraira (may Allah be pleased with him) that when the Messenger of Allah (peace and blessings of Allah be upon him) stood for prayer, he would say the takbeer when he stood up, then when he bowed for ruku he would say the takbeer, then when he raised his back from ruku he would say "Sami' Allahu liman hamidah," then while still standing he would say "Rabbana lakal hamd."
Placing palms on knees in bowing.
It is narrated from Sayyiduna Sa’d bin Abi Waqqas (may Allah be pleased with him) that his son Mus’ab prayed beside him. (Mus’ab) says: I joined both my palms together and then pressed them between my knees, so my father forbade me and said: We used to do this, but we were forbidden from it and were commanded to place our hands (in bowing) on our knees.
Keeping the back straight and being calm in bowing.
Sayyiduna Bara’ (may Allah be pleased with him) says that the bowing (ruku‘) of the Noble Prophet (peace and blessings of Allah be upon him), his prostration (sajdah), his sitting between the two prostrations, and (the state) when he would raise his head from bowing, were all nearly equal in duration, except for the standing (qiyam) and sitting (qu‘ud), which were longer.
