The Prophet (ﷺ) did not attach more importance to any Nawafil prayer than the two Rak'ah of prayer before dawn (Fajr) prayer.[Al-Bukhari and Muslim].

The Messenger of Allah (ﷺ) used to perform two short Rak'ah prayer when it was dawn and the Mu'adhdhin had called Adhan (for the Fajr prayer).[Al-Bukhari and Muslim].

The Messenger of Allah (ﷺ) used to recite during the two Rak'ah of Fajr prayer: "Say (O Muslims): We believe in Allah and that which has been sent down to us..." (2:136) which is in Surat Al-Baqarah in the first Rak'ah and the Verse: "We believe in Allah, and bear witness that we are Muslims (i.e., we submit to Allah." (3:52) in the second Rak'ah.According to another narration, he (ﷺ) recited from Surat Al-'Imran the Verses: "Come to a word which is just between us and you..." (3:64).[Muslim].

When the Prophet (ﷺ) finished the 'Isha prayer, he would perform eleven Rak'ah before the Fajr prayer, concluding each two Rak'ah with Taslim (i.e., saying As-Salamu 'Alaikum) and observing the Witr (odd) at the end. When the Mu'adhdhin finished proclaiming Adhan for the Fajr prayer and it was dawn, he would rise and perform two short Rak'ah, and then would lie down on his right side till the Mu'adhdhin came to (inform) him about Iqamah.[Muslim].

The Prophet (ﷺ) used to perform four Rak'ah before the 'Asr prayer, separating them with Taslim (i.e., offering blessings) on the favourite angels who are near Allah's proximity and the Muslims and the believers who come after them.[At- Tirmidhi].

I saw the principal Companions of Messenger of Allah (ﷺ) rushing to the pillars (of the mosque) to perform two Rak'ah prayers behind them before the Maghrib prayer.[Al-Bukhari].

The Messenger of Allah (ﷺ) said, "When you have finished your (Fard) Salat (prayer) in the mosque, you should observe some of your (Sunnah and Nawafil) Salat at home; Allah will bless your homes because of your Salat (in your homes)."[Muslim]

"Yes, I performed the Friday prayer along with him in the enclosure (Maqsurah), and when the Imam concluded the Salat with Taslim, I stood up in my place and performed the Sunnah prayer. When Mu'awiyah went home, he sent for me (and when I came) he said: "Never do again what you have done. When you have observed the Friday prayer, you must not start another Sunnah prayer till you have spoken to some one or have shifted your place; because the Messenger of Allah (ﷺ) ordered us not to follow up the congregational Salat with any other Salat until we have talked (to some one) or moved from the place."[Muslim].

The Witr prayer is not obligatory as the prescribed Salat (prayers), but the Messenger of Allah (ﷺ) observed it as his regular practice (Sunnah). He (ﷺ) said, "Allah is Witr (single, odd) and loves what is Witr. So perform Witr prayer. O followers of Qur'an, observe Witr (prayer)."[At-Tirmidhi and Abu Dawud].

The Messenger of Allah (ﷺ) said, "He who apprehends that he may not get up in the later part of the night, should observe the Witr prayer in the first part of it; and he who is certain to get up in the last part of it, he should observe Witr at the end of the night, because Salat at the end of the night is attended (by the angels), and that is better."[Muslim].

The Messenger of Allah (ﷺ) said to Bilal (May Allah be pleased with him) "Tell me about the most hopeful act (i.e., one which you deem the most rewarding with Allah) you have done since your acceptance of Islam because I heard the sound of the steps of your shoes in front of me in Jannah." Bilal said: "I do not consider any act more hopeful than that whenever I make Wudu' (or took a bath) in an hour of night or day, I would immediately perform Salat (prayer) for as long as was destined for me to perform."[Al-Bukhari and Muslim].

The Messenger of Allah (ﷺ) said, "If anyone performs Wudu' properly, then comes to the Friday prayer, listens to the Khutbah (religious talk) attentively and keeps silent, his (minor) sins between that Friday and the following Friday will be forgiven, with the addition of three more days; but he who touches pebbles has caused an interruption. "[Muslim].

The Messenger of Allah (ﷺ) said, "When one of you intends to come for the Friday prayer, he should take a bath."[Al-Bukhari and Muslim].

The Messenger of Allah (ﷺ) said, "If a man takes bath on Friday, (or) purifies himself as much as he can with Wudu', oils his hair, applies whatever perfume available in his house, sets forth for the mosque, does not separate two people (to make a seat for himself), performs Salat what is prescribed for him, remains silent when the Imam speaks, his (minor) sins between that Friday and the following Friday will be forgiven."[Al-Bukhari].

The Messenger of Allah (ﷺ) said, "The best month for observing Saum (fasting) after Ramadan is Muharram, and the best Salat after the prescribed Salat is Salat at night."[Muslim].

The Prophet (ﷺ) performed the night prayer in pairs (i.e., Rak'ah) and made it odd number by observing one Rak'ah (as Witr).[Al-Bukhari and Muslim].

One night I joined the Prophet (ﷺ) in his (optional) Salat. He (ﷺ) prolonged the Qiyam (standing) so much that I made up my mind to commit an act of wrong. He was questioned: "What did you intend to do?" He replied: "I intended to sit down and stop following him (in Salat)."[Al-Bukhari and Muslim].

Messenger of Allah (ﷺ) said, "That which differentiates us from the disbelievers and hypocrites is our performance of Salat. He who abandons it, becomes a disbeliever."[At-Tirmidhi].

The Messenger of Allah (ﷺ) said, "The best of the men's rows (in Salat) is the first row and the worst is the last; but the best of the woman's row is the last and the worst of their rows is the first."[Muslim].

The Messenger of Allah (ﷺ) used to gently pat our shoulders when we were standing in rows at the time of Salat and say, "Keep (the rows) straight; do not differ from each other lest your hearts should suffer from discord. Let those of you who are mature and prudent be nearer to me, and then those who are next to them."[Muslim].
