What are the divisions of the Wajib (obligatory), the Mu'akkad (emphasized Sunnah), and the Sunnah, which do not require prostration of forgetfulness (sujud as-sahw) in the Maliki school of thought, along with clarifying the ruling on intentionally or unintentionally omitting each division?

In the Maliki school of thought, the obligations of prayer (also called fara'id or arkan) are 16 matters, including: the intention (niyyah), the opening takbir (takbirat al-ihram), standing, Surah Al-Fatiha, bowing (ruku'), prostration (sujud), standing erect after bowing (i'tidal), tranquility (tumaniyyah), proper order (tartib), the follower's adherence to the imam in the opening takbir and salutation, and the intention to follow the imam.

The sunan are divided into emphasized (mu'akkadah) and unemphasized (ghayr mu'akkadah): - The eight emphasized sunan include: reciting something other than Al-Fatiha, vocalizing and whispering in their appropriate places, saying takbir and tahmid, and the first and second tashahhud and their sittings. - The unemphasized sunan are numerous, including: reciting a surah after Al-Fatiha, some of the takbirat, saying "Allah hears those who praise Him" (sami'a Allahu li-man hamidah), the wording of the tashahhud, invoking blessings upon the Prophet, prostrating on the hands and knees, returning the salutation, having a sutrah (barrier), establishing the prayer (iqamat as-salat), the call to prayer (adhan), and shortening the prayer for the traveler.

As for the desirable acts (mustahabbat), they include: giving the salutation to the right first, saying "Ameen," the qunut in the morning prayer, glorifying Allah in bowing and prostration (tasbih ar-ruku' wa as-sujud), letting the hands hang loosely (sadl al-yadayn), raising the hands with the opening takbir, lengthening and shortening surahs, and the remembrances (adhkar) after prayers.

The consequences of omitting these matters are as follows: - Whoever intentionally omits an obligation (fard) has his prayer invalidated. If he omits it forgetfully, he makes it up, or cancels the rak'ah and performs it anew. - Whoever intentionally omits an emphasized sunnah does not perform the prostration of forgetfulness, and there is a difference of opinion regarding the invalidation of the prayer. If he omits it forgetfully, he performs the prostration of forgetfulness. - Whoever omits an unemphasized sunnah or a desirable act, whether intentionally or forgetfully, owes nothing.
