I said to the Apostle of Allah (peace_be_upon_him): Are
there two prostrations in Surah al-Hajj? He replied: Yes;
if anyone does not make two prostrations, he should not
recite them.
When the Prophet (peace_be_upon_him) uttered the
salutation at the end of the prayer, he used to say: "O
Allah, forgive me my former and latter sins, what I have
kept secret and what I have done openly, and what I have
done extravagance; and what Thou knowest better than I do.
Thou art the Advancer, the Delayer, there is no god but
Thou"
In the year of Conquest the Apostle of Allah (peace_be_upon_him)
recited a verse at which a prostration should be made and
all the people prostrated themselves. Some were mounted,
and some were prostrating themselves on the ground, and
those who were mounted prostrated themselves on their
hands.
The Apostle of Allah (peace_be_upon_him) used to recite
the Qur'an to us. When he came upon the verse containing
prostration, he would utter the takbir (Allah is most
great) and we would prostrate ourselves along with him.
The Apostle of Allah (peace_be_upon_him) prostrated
himself at night when reciting the Qur'an. He said
repeatedly: My face prostrates itself to Him Who created
it and brought forth its hearing and seeing by His might
and power.
AbuTamimah al-Hujaymi said: When we came to Medina
accompanying the caravan, I used to preach after the dawn
prayer, and prostrate on account of the recitation of the
Qur'an. Ibn Umar prohibited me three times, but I did not
cease doing that. He then repeated (his prohibition)
saying: I prayed behind the Apostle of Allah (peace_be_upon_him),
AbuBakr, Umar and Uthman, they would not prostrate (on
account of the recitation of the Qur'an) till the sun had
risen.
