A Hadith can be categorized with regards to its authenticity into basically
4 types, 1) Sahih (authentic), 2) Hasan (sound), 3) Dha’eef (weak), 3.1) Dha
‘eef Jiddan (very weak), and 4) Mawdhoo (fabricated)
The first 2 types can be used as proofs for the different laws in Shari’ah.
The third can be used (with a few conditions attached) to establish virtues
for any specific deed or person. (This is accepted by the vast majority of
the Muhadditheen).
3.1 and 4 cannot be used for anything besides for the purpose of explaining
to somebody it’s classification. They cannot be quoted in any lecture, book,
etc. with the intention of inspiring people through its contents. Rasulullah
(Sallallaahu Alayhi Wasallam) said, ‘He who lies (about a speech) of mine
should prepare his abode in the fire.’ (Bukhari)
Hence, the Ulama have deduced that it is Haraam (forbidden) for one to quote
any fabricated Hadith without explicitly mentioning its fabrication. As for
3.1 (very weak, which is also referred to by the words, ‘very unreliable’),
because of it being so weak, the Ulama have joined it to Mawdhoo
(fabricated) Ahaadith. So, they share the same law as mentioned above. (For
further reference, see Sharh Nukhbatul Firk of Haafiz ibn Hajar;
Tadreeburraawiy of Haafiz Suyyooti and; Al-Ajwibatul fadhilah of Ml. Abdul
Hayy Laknawiy)
