Imam Ibn Rajab al Hanbali (736 - 795 AH) He was the noble Imam, the Haafidh, the Critic, Zayn-ud-Deen ‘Abdur-Rahmaan bin Ahmad bin ‘Abdir-Rahmaan bin al-Hasan bin Muhammad bin Abil-Barakaat Mas’ood As-Salaamee Al-Baghdaadee (due to his place of birth), Al-Hanbalee (due to his madh-hab), Ad-Dimashqee (due to his place of residence and death). His kunyah was Abul-Faraj, and his nickname was Ibn Rajab, which was the nickname of his grandfather who was born in that month (of Rajab).

He was born in Baghdad in 736H and was raised by a knowledgeable family, firmly rooted in knowledge, nobility and righteousness. His father played the greatest role in directing him towards the beneficial knowledge.

Al-Haafidh Ibn Rajab, may Allaah have mercy on him, was deeply attached to the works of Shaikh-ul-Islaam Ibn Taimiyyah, for he would issue legal rulings according to them and would constantly reference his books. This is since he served as a student under Ibn Qayyim al-Jawziyyah, the most outstanding student of Shaikh-ul-Islaam Ibn Taimiyyah, may Allah have mercy on all of them. But in spite of this, he (rahimahullaah) wasn’t a blind follower or a fanatical adherent (to his teacher). Rather, he would review, authenticate, verify and follow the evidences.

Al-Haafidh Ibn Rajab, may Allaah have mercy on him passed to the realm of the Akhira in Ramadaan, 795H. He died while in Damascus.

Siyar A'lam al-Nubala'i, is the most referenced biographical layers of the Muslim Ummah. This is one of the most celebrated books of the Imam al-Dhahabi. 

He was known for his flawless memory of biographical knowledge which Imam ibn Hajar said that he asked Allah to make him as keen as Imam al-Dhahabi in memory. .

This book is a fascinating read, it is an 9th century account of the biography of various leaders at the time. This part is found under the section of the book expounding upon the Mongols, most of whom had not radiated out of central Asia at this time. People have no idea of the treasures in classical Islamic historical works. Most of them are not translated, but most of the stuff that people deem "apologetics" for things such as the hadith are already in there. There are many manuscripts that have compiled commentaries on the entire works of Sahih al-Bukhari and Sahih al-Muslim, for example.

Book written on the great scholar Ibn Hajar al-'Asqalani. His name is Ahmad ibn 'Ali ibn Muhammad ibn Muhammad 'Ali al-Kinani al-Asqalani. His great grandparents lived in Asqalan where they entered it in the year 583H. The word Hajar is the name of one of his grandfathers. His kunya is Abul-Fadl and his Laqab is Shihabuddin. This city Asqalan is found in Palestine in Gaza. Ibn Hajar was born on the 12th of Sha'ban, 773H. Ibn Hajar was an orphan. His father who was a great scholar and merchant died in the year 777H (making Ibn Hajar only four years old). His mother passed away before that and so he was an orphan from both of his parents. Ibn Hajar had an older brother who was very learned, but died before Ibn Hajar and due to this his father became very upset and saddened. One of the pious people saw a dream and he gave glad tidings to the father of Ibn Hajar, and told him that he would be succeeded by a person who would be better than him and have a long life. Ibn Hajar himself then says that, "I was born and Allah subhanahu wa ta'ala opened my hands for me."

Book written on the topic of Ibn Taymiyyah.

Prominent and controversial Syrian thinker, theologian, Hanbali jurist, and political figure. His intellectual activities, preaching, and politics resulted in persecution and imprisonment. Main doctrine was the supremacy and authoritativeness of the Quran and Sunnah of Muhammad and the early Muslim community. Encouraged a literal interpretation of scripture and condemned the popular practices of saint worship and pilgrimages to saints' tombs as worship of other than God. Rejected theology, philosophy, and metaphysical Sufism, although he encouraged pietistic Sufism. Opposed to blind obedience to tradition (taqlid), he favored ijtihad (independent reasoning). Tied Islam to politics and state formation and made a sharp distinction between Islam and non-Islam, noting the difference between a public proclamation of Islam and actions that are inconsistent with Islamic teachings and values. Issued fatwas against the Mongols as unbelievers at heart despite public claims to be Muslim. Influenced later thinkers such as Muhammad ibn Abd al-Wahhab , Hasan al-Banna , and Sayyid Qutb . His authority has been used by some twentieth-century Islamist groups to declare jihad against ruling governments.

Abu 'Abdullah Muhammad ibn Idris al-Shafi'i (150–204 AH/768–820 CE) was born in Gaza and was only two years old when his mother took him to Makkah, where his father’s family came from. He was brought up by his mother, who was a very devout woman, and by the age of seven, al-Shafi'i had completed memorizing the Qur’an, and by 10 he had memorized Al-Muwatta’, the Hadith and Fiqh anthology of Imam Malik. At a young age he joined the desert tribe of Hudhayl, one of the most eloquent Arabian tribes, where he learnt much of their poetry and stayed with them for some years. When he returned to Makkah, he had attained a superior standard of eloquence and knowledge of Arabic.
