Omar said that he offered two units of prayer before and after the mid-day prayer, and
two units of prayer after the evening prayer and two units of prayer after the night prayer
with the Prophet (salla Allahu alihi wa sallam).

The Prophet’s Fast

Other than the obligatory fast of Ramadan, the Prophet (salla Allahu alihi wa sallam)
observed voluntary fasts. Lady Ayesha, may Allah be pleased with her, said that after
the migration to Medina the Prophet (salla Allahu alihi wa sallam) did not fast an entire
month except for the month of Ramadan. She also said in another hadith he would fast
most of the month of Shaaban.

We are also told that he would fast some days of a month and none at all in another. Of
the days he is known to have fasted Monday and Thursday received his special
attention. Lady Ayesha, may Allah be pleased with her, reported the Prophet (salla
Allahu alihi wa sallam) saying: "I was born on a Monday, and the sending down of the
Koran commenced on a Monday." Abu Hurairah, may Allah have mercy on him, said:
"Deeds are presented (to Allah, the Most High) on Mondays and Thursdays. I desire that
my deeds be presented whilst I am fasting."
