Narrated Abu Sa`id Al-Khudri: While I was present in one of the gatherings of the Ansar, Abu Musa came as if he was scared, and said, "I asked permission to enter upon `Umar three times, but I was not given the permission, so I returned." (When `Umar came to know about it) he said to Abu Musa, "Why did you not enter?'. Abu Musa replied, "I asked permission three times, and I was not given it, so I returned, for Allah's Apostle said, "If anyone of you asks the permission to enter thrice, and the permission is not given, then he should return.' " `Umar said, "By Allah! We will ask Abu Musa to bring witnesses for it." (Abu Musa went to a gathering of the Ansar and said). "Did anyone of you hear this from the Prophet ?" Ubai bin Ka`b said, "By Allah, none will go with you but the youngest of the people (as a witness)." (Abu Sa`id) was the youngest of them, so I went with Abu Musa and informed `Umar that the Prophet had said so. (See Hadith No. 277, Vol. 3)

Narrated Abu Huraira: I entered (the house) along with Allah's Apostle . There he found milk in a basin. He said, "O Abu Hirr! Go and call the people of Suffa to me." I went to them and invited them. They came and asked permission to enter, and when it was given, they entered. (See Hadith No. 459 for details)

Narrated Anas bin Malik: that he passed by a group of boys and greeted them and said, "The Prophet used to do so."

Narrated Abu Hazim: Sahl said, "We used to feel happy on Fridays." I asked Sahl, "Why?" He said, "There was an old woman of our acquaintance who used to send somebody to Buda'a (Ibn Maslama said, "Buda'a was a garden of date-palms at Medina). She used to pull out the silq (a kind of vegetable) from its roots and put it in a cooking pot, adding some powdered barley over it (and cook it). After finishing the Jumua (Friday) prayer we used to (pass by her and) greet her, whereupon she would present us with that meal, so we used to feel happy because of that. We used to have neither a midday nap, nor meals, except after the Friday prayer." (See Hadith No. 60, Vol.2)

Narrated Abu Huraira: A man entered the mosque while Allah's Apostle was sitting in one side of the mosque. The man prayed, came, and greeted the Prophet. Allah's Apostle said to him, "Wa 'Alaikas Salam (returned his greeting). Go back and pray as you have not prayed (properly)." The man returned, repeated his prayer, came back and greeted the Prophet. The Prophet said, "Wa alaika-s-Salam (returned his greeting). Go back and pray again as you have not prayed (properly)." The man said at the second or third time, "O Allah's Apostle! Kindly teach me how to pray". The Prophet said, "When you stand for prayer, perform ablution properly and then face the Qibla and say Takbir (Allahu-Akbar), and then recite what you know from the Qur'an, and then bow with calmness till you feel at ease then rise from bowing, till you stand straight, and then prostrate calmly (and remain in prostration) till you feel at ease, and then raise (your head) and sit with calmness till you feel at ease and then prostrate with calmness (and remain in prostration) till you feel at ease, and then raise (your head) and sit with calmness till you feel at ease in the sitting position, and do likewise in whole of your prayer." And Abu Usama added, "Till you stand straight." (See Hadith No. 759, Vol.1)

Narrated Abu Huraira: The Prophet said (in the above narration No. 268), "And then raise your head till you feel at ease while sitting. "
