Where the rule of the shariah is the asl, and there is no consideration for human limitations on whether it can be done or not, it is imposed upon everyone across the board. There are 4 types:

  1. Fard or Fard i’tiqaadi
    1. It is lazim - obligatory, proven with a daleel Qat’i
    2. To miss is a major sin (unless shariah permits an excuse)
    3. The reward for it is also Qat’i
    4. You must believe that it is fard
    5. Denial is kufr
    6. Example: Salah, it is proven from the Qur’an, and the reward is proven from the Qur’an
    7. There are some faraa’id that the scholars differ upon, this is called fard ‘amali, you must believe in it, however the performing it is differed upon
  2. Wajib
    1. It is also lazim - obligatory, proven from a daleel Dhannee
    2. To not do it is makruh tahrimi and a minor sin
    3. Persistence upon it becomes a major sin
    4. Its reward is evident from daleel Dhannee, and therefore not lazim to believe in it
    5. The one who rejects or denounces it is not a kafir, but is considered misguided
    6. The difference between wajib and sunnah mu’akkadah:
      1. Wajib is something the Prophet ﷺ did all His life, and mentioned a punishment for not doing it
      2. Sunnah mu’akkadah is something the Prophet ﷺ did all His life, and did not mentioned a punishment for not doing it
  3. Sunnah
    1. There are 2 types of sunnahs:
      1. Sunan ul-hudaa i.e. sunnah mu’akkadah (emphasised)
        1. To do it is rewarding, to not do it can become sinful
        2. The ahnaaf believe that consistently missing them will deprive one of the intercession of the Prophet ﷺ
        3. It is something that the Prophet ﷺ did all his lifetime as a form of worship
        4. Example: Adhaan, Iqamah
      2. Sunan zaa’idah i.e. sunnah ghayr mu’akkadah (non emphasised)
        1. Actions of the Prophet ﷺ done habitually, and not as a form of worship
  4. Nafl
    1. To do it is rewarding with the correct intention
    2. To miss it, is not a sin, nor is he condemned on the day of judgement
    3. It is any amr that is additional to fard and wajib which the shariah has permitted
    4. The ahnaf say if you start a nafl and you break it, then it becomes lazim upon yourself Muhammad:33
