As Salaamu alaikum wa rahmatullahi wa barakaatuhu
In a class, our brother Abu Yusuf Khaleefah mentioned that the Sunnah is divided into 5 categories which are:
1. The Sunnah connected to Creed (Aqeedah), What The Prophet (SalAllaahu alayhe wa sallam) believed.
2. The verbal Sunnah, What The Prophet (SalAllaahu alayhe wa sallam) said and stated.
3. The physical Sunnah, The Prophet’s (SalAllaahu alayhe wa sallam) actions.
4. The approved Sunnah, The things The Prophet (SalAllaahu alayhe wa sallam) approved of by way of silence.
5. The Sunnah of abandonment, What The Prophet (SalAllaahu alayhe wa sallam) abandoned (left off doing for the pleasure of Allaah).
