After the Quran, below mentioned 6 books form the cornerstone of the details of Islamic teachings as they provide a further elaboration of the Quran’s sayings and commandments.
Books that form part of the authentic six collection are the following:
” Kutub al-Sittah (The Six Books of Hadith)”
1. Sahih Bukhari, collected by Imam Bukhari (AD 870), includes 7000+ ahadith
2. Sahih Muslim, collected by Muslim b. al-Hajjaj (AD 875), includes 9000+ ahadith
3. Sunan al-Nasa’i, collected by al-Nasa’i (AD 915)
4. Sunan Abu Dawood, collected by Abu Dawood (AD 888)
5. Jami al-Tirmidhi, collected by al-Tirmidhi (AD 892)
6. Sunan ibn Majah, collected by Ibn Majah (AD 887)
Besides the above, there are also the nine books , including those six and also three : Book of Imam Ahmed it called Almusnad, Book of Imam Malik called Almowatta’ and Book of Imam Aldaremi called sunan Aldaremi , they are in same level of the six books .
These Ahadith books are considered to be authentic. The name of book is always written in the bracket at the end of the hadith. So we can easily sort them out. As nowadays we find so many fabricated and Da’eef (Weak) hadith, as da’eef hadith is a type of Hadith that had a narrator who either had a weak memory or wasn’t virtuous. So before quoting any hadith, we should check its authenticity otherwise we unknowingly ascribing false things to me which will count as a sin.
The Holy Prophet pbuh said: “He who tells a lie on me intentionally, let him take his seat in the Hellfire. (Bukhari )
That the Prophet of Allah pbhb said in a sermon: “The best speech is that which is embodied in the Book of Allah, the Al Quran; and the best guidance is the guidance given by me, Mohamed (saws). The most evil affairs are the innovations (bida), and every innovation (bida) is an error”. (Abu-Dawood)
And Allah knows best.
