(ii) Sahih Muslim (صحيح مسلم)
Sahih Muslim was compiled by Imam Abū al-Ḥusayn Asākir ad-Dīn Muslim ibn al-Ḥajjāj ibn Muslim ibn Ward ibn Kawshādh al-Qushayrī an-Naysābūrī ( أبو الحسين عساكر الدين مسلم بن الحجاج بن مسلم بن وَرْد بن كوشاذ القشيري النيسابوري), 815–875/206-261 AH (رضئ اللہ تعالی عنہ).
Muslim is considered to be the second most reliable book of Ahadith. It contains around 7,500 Ahadith selected from over 3,00,000 Ahadith.
Imam Muslim took great care in selecting Ahadith for his book. We will not go into details here, except that he kept in view the difference between the two well known modes of narration, 'he narrated to us (Haddathana - حدثنا), and 'he informed us' (Akhbarana - اخبرنا ). The first mode is used when the teacher is narrating the Hadith and the student is listening to it, while the second mode of expression implies that the student is reading the Hadith before the teacher. Imam Bukhari, while describing the chain of narrators, sometimes mentions their kunya (nick name) and sometimes gives their names. But Imam Muslim took particular care in according the exact words of the narrators and points out even the minutest difference in the wording of their reports with narrators names and kunya.
(iii) Sunan an-Nasa'i
Sunan an-Nasa'i was compiled by Imam Abū Abdur Raḥmān Aḥmad ibn Shu`ayb ibn Alī ibn Sīnān al-Nasā'ī (امام عبد الرحمن احمد ابنِ شعيب ابن علي سنان النسائي), 303 915/214 -829 AH, (رضئ اللہ تعالی عنہ).
Imam An-Nasa'i has written two books of Ahadith, (i) A large collection of Ahadith titled 'As-Sunan al-Kubra' (السنن الكبرا), and (ii) Small collection of Ahadith titled 'As-Sunan as-Sughra' (السنن الصغرا). Sunan al-Sughra (السنن الصغرا) is included in Six major collections of Ahadith. It contains over 5,700 Ahadith. Imam Nasai's style is a combination of Bukhari and Muslim. He records different chains of Ahadith then explains the correct one. It is reported that many of his Ahadith are taken from Imam Ahmed bin Hanbal's works.
(iv) Sunan Abu Dawood
Sunan Abu Dawood was compiled by Imam Abu Dawood Sulaymān ibn al-Ash‘ath al-Azdi as-Sijistani ( أبو داود سليمان بن الأشعث الأزدي السجستاني), 816–889/202-275 AH (رضئ اللہ تعالی عنہ). It is one of the six major collection of Ahadith books containing 5,274 Ahadith, mostly related to Islamic Jurisprudence. It is reported that these Ahadith were selected from over 500,000 Ahadith.
(v) Jami at-Tirmidhi
Jami at-Tirmidhi was compiled by Imam Abū Īsá Muḥammad ibn Īsá as-Sulamī aḍ-Ḍarīr al-Būghī at-Tirmidhi (أبو عيسى محمد بن عيسى السلمي الضرير البوغي الترمذي), 824–892/209-279 AH (رضئ اللہ تعالی عنہ). His teachers include, Imam Bukhari, Imam Muslim and Imam Abu Dawood.
(vi) Sunan ibn Majah
Sunan Ibn Majah was compiled by Abū Abdullāh Muḥammad ibn Yazīd Ibn Mājah al-Rabʻī al-Qazwīnī (ابو عبد الله محمد بن يزيد بن ماجه الربعي القزويني), 824–887/209-273 AH (رضئ اللہ تعالی عنہ). It contains 4341 Ahadith spread over thirty seven books. It includes 1339 Aḥādīth, known as Zawā’id of Sunan Ibn Mājah that are not available in other five major Ahadith books.
