Abu Sa'id al-Khudri · The Book on Salat (Prayer)

Allah's Messenger said: "Whenyou hear the call (to prayer) then say the similar to what the Mu'adh-dhin says"

"A man came when Allah's Messenger had already prayed, so he said: 'Which of you will give some reward to this person?' So a man stood to pray with him."

Allah's Messenger said: "the key to Salat is the purification, its Tahrim is the Takbir, and its Tahlilis the Taslim, and there is no Salat for one who did not recite Al-Hamd and a Surah in the obligatory (prayer) or other prayers."

"When Allah;s Messenger stood for Salat during the night, he would say the Takbir (Allahu Akbar), then say: (Subhanaka Allahumma wa bihamdika wa Tabarakasmuka wa Ta'ala Jadduka wa la ilaha ghairuk.) 'Glorious You are O Allah, and with Your praise, and blesses is Your Name, and exalted is Your majesty, and none has the right to be worshipped but You' Then he would say: (A'udhu Bilahi As-Sami'il-Alimi min Ash-Shaitanir-Rajimi, min Hamzihi Wa Nafkhihi wa Nafthihi.)" 'Allah is undoubtedly the greatest.'…

Allah's Messenger said: "All of the earth is a Masjid except for the graveyard and the washroom."

"A man from Banu Khudrah and a man from Banu Amr bin Awf were disputing about the Masjid that was founded upon Taqwa. The man from Banu Khudrah said: 'It is the Masjid of Allah's Messenger.' The other one said that it was Masjid Qub. So they went to ask Allah's Messenger about that. He said: 'It is this - meaning his Masjid - 'and in that one (Masjid Quba) there is much good.'"

Allah's Messenger said: "A mount is not saddled (for a journey) except to three Masajid: Al-Masjid Al-Haram, this Masjid of mine, and Masjid Al-Aqsa." This Hadith is Hasan Sahih.

"The Prophet performed Salat on a Hasir."
