Narrated Nafi`: Ibn `Umar said, "While the Prophet (sallallahu 'alaihi wa sallam) was on the pulpit, a man asked him how to offer the night prayers. He replied, 'Pray two rak`at at a time and then two and then two and so on, and if you are afraid of the dawn (the approach of the time of the Fajr prayer) pray one rak`a and that will be the witr for all the rak`at which you have offered." Ibn `Umar said, "The last rak`at of the night prayer should be odd, for the Prophet (sallallahu 'alaihi wa sallam) ordered it to be so.

Narrated Ibn `Umar: A man came to the Prophet (sallallahu 'alaihi wa sallam) while he was delivering the sermon and asked him how to offer the night prayers. The Prophet (sallallahu 'alaihi wa sallam) replied, 'Pray two rak`at at a time and then two and then two and so on and if you are afraid of dawn (the approach of the time of the Fajr prayer) pray one rak`a and that will be the with for all the rak`at which you have prayed." Narrated 'Ubaidullah bin `Abdullah bin `Umar: A man called the Prophet (sallallahu 'alaihi wa sallam) while he was in the mosque.

Narrated Abu Waqid al-Laithi: While Allah's Messenger (sallallahu 'alaihi wa sallam) was sitting in the mosque (with some people) three men came, two of them came in front of Allah's Messenger (sallallahu 'alaihi wa sallam) and the third one went away, and then one of them found a place in the circle and sat there while the second man sat behind the gathering, and the third one went away. When Allah's Messenger (sallallahu 'alaihi wa sallam) finished his preaching, he said, "Shall I tell you about these three persons? One of them betook himself to Allah and so Allah accepted him and accommodated him; the second felt shy before Allah so Allah did the same for him and sheltered him in His Mercy (and did not punish him), while the third turned his face from Allah, and went away, so Allah turned His face from him likewise.
