Praying at Night in Ramadhan

[Dan]

Bismillah


As Salam alaikum


Volume 3, Book 32, Number 230:


Narrated Abu Salama bin 'Abdur Rahman:


that he asked 'Aisha "How was the prayer of Allah's Apostle in Ramadan?" She replied, "He did not pray more than eleven Rakat in Ramadan or in any other month. He used to pray four Rakat ---- let alone their beauty and length----and then he would pray four ----let alone their beauty and length ----and then he would pray three Rakat (Witr)." She added, "I asked, 'O Allah's Apostle! Do you sleep before praying the Witr?' He replied, 'O 'Aisha! My eyes sleep but my heart does not sleep."


I am not trying to be argumentative but I came across this and others. I have not seen a hadith that has the number 20 in it. The closest in one about the Prophet praying two by two rakats but no number is specified.


As Salam alaikum wa rahmatullahi wa barakatu
