Sunan Abu Dawud Volume 1-5 [Compressed]

Ijadith is next only to Qur'ân as a source of Islamic laws and proofs. The term
Hadith applies to the words and acts of Allah's Messenger �
as well as his
tacit approvals called Taqrir. The latter refers to acts done in his presence but
he did not disapprove of them, his silence indicating his approval. All these
three categories of A,adith are variously known as (1) Khabar, (2) Athar, (3)
Hadith and (4) Sunnah. (All these words have already been mentioned under
the technical terms employed by Ijadith scholars).
