A: The acts whose merits are explained in the Qur'an and Sunnah are of two types: 1­ Obligatory acts,

which a Muslim ­ whether a scholar or not ­ must be mindful to their performance, fearing Allah regarding their regular observation. Among the rituals of this type are the Five Obligatory Daily Prayers, giving Zakah (obligatory charity), and the other obligatory acts. 2­ Mustahab (desirable) acts, such as performing Tahajjud (optional late night Prayer), Salat­ul­Duha (supererogatory Prayer before noon) ...etc. Muslims, especially those of profound knowledge and who are role models, should do their best and be consistent in the performance of these supererogatory acts of devotions. However, if one is preoccupied, or was irregular in doing such acts for a while, there is no harm in this because these acts are only Nafilah (supererogatory). Nevertheless, it is a quality of the of people of knowledge, and righteous people in general, to be mindful of their worship and observe supererogatory prayers, such as Tahajjud during the night, Salat­ul­Duha, Al­ Sunan Al­Rawatib (supererogatory acts that were stressed and regularly performed by the Prophet), and other righteous acts.
