The Reward of Adhering to the Rawatib Prayers

Question:
Some people are lax regarding the rawatib (the regular voluntary prayers attached to the obligatory ones). What is the reward for adhering to these sunnahs? Do they carry a reward? And do they complete the obligatory acts?

Answer:
Yes, the rawatib prayers that accompany the obligatory prayers are twenty rak'ahs: two before the midday prayer, two after it, two after the sunset prayer, two after the night prayer, and two before the dawn prayer. These two are the most emphasized of the rawatib. A Muslim should adhere to these, except when he shortens the prayer while traveling. If he shortens the prayer while traveling, he does not perform the rawatib. Ibn 'Umar (may Allah be pleased with him and his father) said, "If I were praying voluntary prayers, I would complete them." Yes.
