What are Hadiths?
A hadith is anything reported from Prophet Muhammad ﷺ in terms of his sayings, actions, tacit approvals, or physical and moral descriptions. Hadiths constitute the second source of Islamic legislation after the Quran and form the Sunnah (Prophetic tradition). Allah says: "Whatever the Messenger gives you, take it; and whatever he forbids you, abstain from it." (Surah Al-Hashr, 59:7). Hadiths explain the Quran, detail its rulings, and clarify its general terms — they are the practical application of what is contained in the Book of Allah. The Companions took great care to preserve the Prophet's ﷺ words and transmit them faithfully and accurately, and scholars continued to collect, record, and verify them over the centuries. Hadiths cover every aspect of life: worship, transactions, morality, etiquette, medicine, and social relations.
The Science of Hadith (Ulum al-Hadith)
The sciences of hadith (Ulum al-Hadith) are a set of disciplines developed by Muslim scholars to verify the authenticity of prophetic hadiths. Each hadith consists of two parts: the Isnad (chain of transmission) and the Matn (text of the hadith). Hadiths are classified by their degree of authenticity: Sahih (authentic) is the highest, with conditions of continuous chain, reliability and precision of transmitters, and absence of irregularity or defect. Then comes Hasan (good), where one transmitter has slightly lesser precision. Then Da'if (weak), which fails to meet one or more conditions of authenticity. Finally, Mawdu (fabricated), which is proven to be invented. Hadith scholars developed a unique critical methodology for evaluating transmitters known as Jarh wa Ta'dil (criticism and endorsement), where each transmitter is studied for their integrity, precision, and memory. This critical methodology is unparalleled in the history of human civilizations.
The Six Major Collections (Kutub al-Sittah)
The Kutub al-Sittah (Six Collections) are the most important hadith collections for Sunni Muslims. The first and most authentic is Sahih al-Bukhari by Imam Muhammad ibn Ismail al-Bukhari (d. 256 AH), which contains approximately 7,275 hadiths selected from 600,000. The second is Sahih Muslim by Imam Muslim ibn al-Hajjaj (d. 261 AH). These two works are known as "the Two Sahihs," and hadiths upon which they agree reach the highest degree of authenticity. Then come the Sunan of Abu Dawud by Abu Dawud al-Sijistani (d. 275 AH), which focuses on hadiths of legal rulings. The Sunan al-Tirmidhi by Abu Isa al-Tirmidhi (d. 279 AH) is distinguished by mentioning the grading of each hadith. The Sunan of al-Nasa'i by Abu Abdurrahman al-Nasa'i (d. 303 AH) is renowned for its rigor in evaluating transmitters. Finally, the Sunan of Ibn Majah by Ibn Majah al-Qazwini (d. 273 AH). These collections represent the scholarly culmination of centuries of verification and examination.
How Were Hadiths Preserved?
The preservation of hadiths began during the Prophet's ﷺ own lifetime, with the Companions memorizing his words and applying them in their lives. Some wrote them down, such as Abdullah ibn Amr ibn al-As, who had a manuscript known as al-Sahifa al-Sadiqa. After the Prophet's ﷺ death, the Companions transmitted hadiths to the Tabi'in (successors) faithfully, and the Tabi'in to their successors. Under Caliph Umar ibn Abd al-Aziz (d. 101 AH), the official compilation of hadiths began. Then came the era of classification and categorization in the 2nd and 3rd centuries AH, with the emergence of Musannaf, Musnad, and Sunan works. Scholars developed a rigorous methodology to verify each hadith, including studying every transmitter in the chain and comparing different narrations of the same hadith. This methodology is considered one of the greatest achievements of Islamic civilization in heritage preservation.
Importance of Hadiths in Islamic Law
Prophetic hadiths play a central role in Islamic legislation. They explain what is mentioned generally in the Quran: for example, the Quran commands prayer, but hadiths detail its method, times, pillars, and conditions. Similarly with Zakat, Hajj, and fasting — the details of these acts of worship are explained by the Sunnah. Hadiths restrict what is stated absolutely in the Quran and specify what is general. The Sunnah also establishes new rulings not mentioned in the Quran, such as the prohibition of marrying a woman along with her paternal or maternal aunt. Scholars unanimously agree that the Sunnah is an independent source of legislation. The Prophet ﷺ said: "I have been given the Book and its equivalent along with it." (Abu Dawud). Therefore, a correct understanding of Islam can only be achieved by combining the Quran and the Sunnah together.
How to Study Hadiths?
Beginners are advised to start with "The Forty Hadith" by Imam al-Nawawi, a collection of 42 hadiths covering the foundations and major principles of the religion. Then move to "Riyad as-Salihin" (Gardens of the Righteous), also by Imam al-Nawawi, a comprehensive book on morals, etiquette, and encouragement toward good deeds. After that, one can study "Bulugh al-Maram" by Ibn Hajar al-Asqalani, dedicated to hadiths of legal rulings. When studying a hadith, it is important to verify its authenticity by referring to authentication works and scholars' opinions. It is also recommended to study hadith commentaries to understand their deep meanings and practical applications. Among the most famous commentaries are "Fath al-Bari" by Ibn Hajar, a commentary on Sahih al-Bukhari, and Imam al-Nawawi's commentary on Sahih Muslim. Reliable digital applications like ours provide easy access to authentic hadiths with their references and gradings.
