"I asked ‘A'isha (may Allah the Exalted be well pleased with her): “Did the Prophet (Allah bless him and give him peace) perform the mid-morning ritual prayer?” She said: “Yes, four cycles, and he used to add whatever Allah wished (Almighty and Glorious is He).”

“The Prophet (Allah bless him and give him peace) used to perform the mid-morning ritual prayer in six cycles.”

“I have never heard anyone mention seeing the Prophet (Allah bless him and give him peace) performing the mid¬morning ritual prayer except Umm Hani (may Allah the Exalted be well pleased with her). “She related that Allah’s Messenger (Allah bless him and give him peace) entered her house on the Day of the Conquest of Mecca, whereupon he performed the major ritual ablution and glorified Allah in eight cycles. I never saw him (Allah bless him and give him peace) perform a ritual prayer in a more abbreviated form than that, even though he completed the bowing [ruku] and the prostration [sujud]!”

“I asked 'A'isha (may Allah the Exalted be well pleased with her): ‘Was the Prophet (Allah bless him and give him peace) used to performing the mid-morning ritual prayer?’ She said: ‘No, except when he was coming back from an absence.'"

"The Prophet (Allah bless him and give him peace) would perform the mid-morning ritual prayer so often that we would say: “He does not omit it,” and he would omit it so often that we would say: “He does not perform it!”

“The Prophet (Allah bless him and give him peace) used to devote himself to four cycles [of ritual prayer] at high noon, so I said: ‘O Messenger of Allah, you devote yourself to these four cycles at high noon!’ He explained: ‘The gates of heaven are opened at high noon, then they are unlocked until the midday ritual prayer is performed, so I love to have a good deed ascend on my behalf during that time!’ I said: ‘Is there a Qur’anic recitation in each of them [the four cycles]?’ He said: ‘Yes!’ I said: ‘Do they contain a separating salutation of peace?’ He said: ‘No!'”Another chain reports a similar narration.

“Allah’s Messenger (Allah bless him and give him peace) used to perform four cycles of ritual prayer after the sun had passed its zenith before the noon prayer, and he said: 'It is a time in which the gates of heaven are opened, so I love to have a righteous deed ascend for me then!'”

"He used to perform four cycles of ritual prayer before noon", and he mentioned that Allah’s Messenger (Allah bless him and give him peace) used to perform them at the time of the sun's zenith, and he used to prolong them.
