A hadith states that the number of rawatib (regular voluntary prayers) is ten, while another hadith states that they are twelve. How are these two reconciled?

Question:
The Honorable Shaykh, may Allah grant you success, asks: How do we reconcile the number of rak'ahs of the rawatib (regular voluntary prayers) mentioned by the jurists, which is ten, with the hadith of the Prophet (peace and blessings be upon him) who said, "Whoever prays twelve rak'ahs for Allah in a day and a night, Allah will build for him a house in Paradise"?

Answer:
Yes. These ten are in the hadith of Ibn 'Umar. The addition of these comes from other hadiths: four before Dhuhr, and four before and after Dhuhr—four before Dhuhr and four after it. So what is the total? Fourteen rak'ahs. That means two were added before and two after the ten. What is the total? Fourteen. Yes. Also, there are four before 'Asr, but they are not rawatib. Four before 'Asr, but they are purely voluntary (nafilah) and not rawatib, because 'Asr has no rawatib, neither before nor after it. So these four are purely voluntary.
