two rak`at before the Fajr prayer so light

Sahih Bukhari 2.262:

Narrated `Aisha: The Prophet (p.b.u.h) used to make the two rak`at before the Fajr prayer so light that I would wonder whether he recited Al−Fatiha (or not).

Important of Sunna of the Fajr prayer

Sahih Bukhari 2.260

Narrated `Aisha: The Prophet was never more regular and particular in offering any Nawafil than the two rak`at (Sunna) of the Fajr prayer.

His prayer will be accepted

Sahih Bukhari 2.253 :

Narrated 'Ubada bin As−Samit: The Prophet "Whoever gets up at night and says: −− 'La ilaha il−lallah Wahdahu la Sharika lahu Lahu−l−mulk, waLahu−l−hamd wahuwa 'ala kullishai'in Qadir. Al hamdu lil−lahi wa subhanal−lahi wa la−ilaha il−lal−lah wa−l−lahu akbar wa la hawla Wala Quwata il−la−bil−lah.' (None has the right to be worshipped but Allah. He is the Only One and has no partners . For Him is the Kingdom and all the praises are due for Him. He is Omnipotent. All the praises are for Allah. All the glories are for Allah. And none has the right to be worshipped but Allah, And Allah is Great And there is neither Might nor Power Except with Allah). And then says: −− Allahumma, Ighfir li (O Allah! Forgive me). Or invokes (Allah), he will be responded to and if he performs ablution (and prays), his prayer will be accepted."

"How is the night prayer of the Prophet?"

Sahih Bukhari 2.247

Narrated Al−Aswad: I asked `Aisha "How is the night prayer of the Prophet?" She replied, "He used to sleep early at night, and get up in its last part to pray, and then return to his bed. When the Mu'adh−dhin pronounced the Adhan, he would get up. If he was in need of a bath he would take it; otherwise he would perform ablution and then go out (for the prayer)."

Special in last third of the night

Sahih Bukhari 2.246

Narrated Abu Huraira: Allah's Apostle (p.b.u.h) said, "Our Lord, the Blessed, the Superior, comes every night down on the nearest Heaven to us when the last third of the night remains, saying: "Is there anyone to invoke Me, so that I may respond to invocation? Is there anyone to ask Me, so that I may grant him his request? Is there anyone seeking My forgiveness, so that I may forgive him?"

Masjid Aisha

Masjid Aisha, also known as Masjid at-Tan’eem marks the place where Ummul-Mu’mineen Aisha (may Allah be pleased with her) went to enter into Ihram for Umrah when the Prophet (peace and blessings of Allah be on him) told her to do so during the farewell Hajj. The masjid lies 7.5 km south from Makkah on the road to Madinah and is the closest of all the boundary points.

• Jaabir (may Allah be pleased with him) reports that because Aisha (may Allah be pleased with her) was experiencing menstrual cycle the Prophet (peace and blessings of Allah be on him) instructed her to perform all the various rites of Hajj except for the tawaf. She then performed the tawaaf after her cycle had ended. She then said, “O Rasulullah (peace and blessings of Allah be on him)! While you have performed Hajj and Umrah, I have performed only Hajj.” The Prophet (peace and blessings of Allah be on him) then instructed her brother Abdur-Rahman (may Allah be pleased with him) to take her to Tan’eem and it was from there that she performed her Umrah after her Hajj during the month of Dhul Hijjah.

three knots

Sahih Bukhari 2.237: Narrated Hudhaifa : Whenever the Prophet got up for Tahajjud prayer he used to clean his mouth (and teeth) with Siwak.

Sahih Bukhari 2.243: Narrated Abu Huraira Allah's Apostle said, "Satan puts three knots at the back of the head of any of you if he is asleep. On every knot he reads and exhales the following words, 'The night is long, so stay asleep.' When one wakes up and remembers Allah, one knot is undone; and when one performs ablution, the second knot is undone, and when one prays the third knot is undone and one gets up energetic with a good heart in the morning; otherwise one gets up lazy and with a mischievous heart."
