Narrated `Aisha: Allah's Apostle used to give up a good deed, although he loved to do it, for fear that people might act on it and it might be made compulsory for them. The Prophet never prayed the Duha prayer, but I offer it.

Narrated `Aisha the mother of the faithful believers: One night Allah's Apostle offered the prayer in the Mosque and the people followed him. The next night he also offered the prayer and too many people gathered. On the third and the fourth nights more people gathered, but Allah's Apostle did not come out to them. In the morning he said, "I saw what you were doing and nothing but the fear that it (i.e. the prayer) might be enjoined on you, stopped me from coming to you." And that happened in the month of Ramadan.

Narrated Al-Mughira: The Prophet used to stand (in the prayer) or pray till both his feet or legs swelled. He was asked why (he offered such an unbearable prayer) and he said, "should I not be a thankful slave."

Narrated `Abdullah bin `Amr bin Al-`As: Allah's Apostle told me, "The most beloved prayer to Allah is that of David and the most beloved fasts to Allah are those of David. He used to sleep for half of the night and then pray for one third of the night and again sleep for its sixth part and used to fast on alternate days."

Narrated Masruq: I asked `Aisha which deed was most loved by the Prophet. She said, "A deed done continuously." I further asked, "When did he used to get up (in the night for the prayer)." She said, "He used to get up on hearing the crowing of a cock." Narrated Al-Ashath: He (the Prophet (p.b.u.h) ) used to get up for the prayer on hearing the crowing of a cock.

Narrated `Aisha: In my house he (Prophet (p.b.u.h) ) never passed the last hours of the night but sleeping.

Narrated Qatada: Anas bin Malik said, "The Prophet (p.b.u.h) and Zaid bin Thabit took their Suhur together. When they finished it, the Prophet stood for the (Fajr) prayer and offered it." We asked Anas, "What was the interval between their finishing the Suhur and the starting of the morning prayer?" Anas replied, "It was equal to the time taken by a person in reciting fifty verses of the Qur'an."

Narrated Abu-Wail: `Abdullah said, "One night I offered the Tahajjud prayer with the Prophet and he kept on standing till an ill-thought came to me." We said, "What was the ill-thought?" He said, "It was to sit down and leave the Prophet (standing)."

Narrated Hudhaifa: Whenever the Prophet got up for Tahajjud prayer he used to clean his mouth (and teeth) with Siwak.
