What is the ruling on performing two rak'ahs before the obligatory prayer, other than the greeting of the mosque?

Question:
Is it recommended to perform two rak'ahs before the obligatory prayer, other than the greeting of the mosque?

Answer:
The rawatib (regular voluntary prayers) before the prayer, this does not exist except before the midday prayer only. The midday prayer has a rawatib before it and a rawatib after it. The afternoon prayer has no rawatib, neither before it nor after it. The sunset prayer has a rawatib after it. The night prayer has a rawatib after it. The dawn prayer has a rawatib before it. So the ones that have a rawatib before them are two prayers: the midday and the dawn. As for the remaining prayers, like the sunset and the night, their rawatib are after them. And as for the afternoon, it has no rawatib, neither before it nor after it. But whoever prays before the afternoon whatever voluntary prayer (nafilah) is easy for him, there is no harm.
