Hafsah reports: “The Prophet would pray the two rak’at of fajr before the dawn in my house and he would make it very quick.” Naf’i states: “Abdullah [Ibn 'Umar] would also make it very quickly.” This is related by Ahmad, al-Bukhari, and Muslim.
‘Aishah narrates: “The Prophet would pray the two rak’at before the dawn prayer in my house so quickly that I wondered if he had recited the Fatihah in them or not.”
This is related by Ahmad and others. She also said: “When the Prophet prayed the two rak’at before the dawn prayer I estimated the time that he took in recital was like what it takes to recite al-Fatihah. This is related by Ahmad, an-Nasa’i, al-Baihaqi, Malik, and at-Tahawi.

Prayer @ the Speed of Thought ?
B.R.Raheem
Ahle Taqleed (wahabiya, salafiya, moududiya, etc) pay attention on every step of the salah and misrepresent khush wa khudu as slow motion…….thats why those who are mislead by wahabiya and other dajali firqh’s collectively called ahle Taqleed,object to a person who zips through sunnah or nawafil……
Even though the a-Hadith e Rasool mentioned above are valid yet this was not the “must-to-do” for the followers of the prophet……so one has to pray with proper decor as one is present in the court of divinity and should not cause confusions for others by zipping through as if he is not in the presence of a divine power…thats the problem , ahle taqleed and dajali groups get upset at the speed of the salah which they mis translate as “absence of Huzoor” ….(attention)
My opinion might not be valid so take it if it benefits , and dump it if is confusing…
Mulla!
