Does one pray the Sunnah of Dhuhr as two rak'ahs or four rak'ahs?

The questioner : May Allah bless you. This Sunnah, and what is similar to it, such as the Sunnah of Dhuhr, was reported as being either two or four. Does a person stick to the greater number because it is better, or does he vary it, sometimes doing this and sometimes that?

The Shaykh : The four were not reported as being the established practice.

The questioner : It is natural.

The Shaykh : The issue is established as being the returning practice.

The questioner : Two or...

The Shaykh : In al-Bukhari and others.

The questioner : Yes, Shaykh.

The Shaykh : No, he does not pray four. And the fact that Ibn 'Umar prayed two in his house, he said that is what he saw, and 'Aishah said he used to pray four.
