The Sunnah which has an important bearing on Islamic Law is only the Sunnah confirmed by scientific channels, and authentic chains of narrations known to the learned in regard to hadeeths and the background of the narrators.
It is not the one which is found in different works of Tafseers (commentaries of The Qur'an) and Islamic jurisprudence (fiqh), and in different writings of longing, intimidation, advices, and admonitions, etc...
They contain weak, spurious, and fabricated hadeeths, of which Islam absolves, like the story of 'Harut and Marut,' and the sotry of 'gharanik.' I have a special letter which makes it void and it is printed. A major part of it is recorded in two huge books namely "A chain of weak and fabricated hadeeths and their evil impact on the community." Their number upto date have reached approximately four thousand hadeeths.
It is obligatory on the learned, especially those who spread the knowledge of fiqh and legal opinions among the public, that they shouldn't dare to argue with hadeeth unless it is well-attested. Books of jurisprudence, which they refer to, are normally filled with traditions which are not well-attested, nor have any bases, as is well-known to the learned.
I have begun an important project, and I think it will be of use to those occupied with jurisprudence, and I will name it: "Weak and Fabricated Hadeeths in the Major Jurisprudence 'fiqh' Books," by which I mean:
- Al-Hidayah, by Al-Marghinani, in Hanafi fiqh,
- Al-Modawwanah, by Ibnil-Qasim, in Maliki fiqh,
- Sharhul-wajeez, by Al-rafiee, in Shafiee fiqh,
- Al-Mughni, by Ibn Quddamah, in Hanbali fiqh, and
- Bidayatul Mujtahid, by Ibn Rushd-al-Andalusi, in comparative fiqh.
I regret that I did not get the opportunity to finish it, because the journal "Al-Wa'e-al-Islami" of Kuwait which promised to publish it, when perused it, didn't print it.
Although I missed this opportunity, perhaps I will succeed on another occasion, Allah willing, to offer to my bretheren occupied with jurisprudence a precise learned course to help them to facilitate their knowledge of the different categories of hadeeth with reference to various sources from books on hadeeth, with an explanation of its special nature and character and reliance on them. Allah is the source of success.
