The author of the main text is 14th-century scholar Shihabuddin Abu al-'Abbas Ahmad ibn an-Naqib al-Misri (AH 702-769 / AD 1302–1367).

Al-Misri based his work on the previous Shafi'i works of Imam Nawawi and Imam Abu Ishaq as-Shirazi, following the order of Shirazi's al-Muhadhdhab (The Rarefaction) and the conclusions of Nawawi's Minhaj at-Talibin (The Seeker's Road).

As recently as 1991, Reliance of the Traveller became the first standard Islamic legal reference to be translated into English (or any of the European languages), to be certified by Al-Azhar University in Egypt.

Following are translations of eight shorter works - Books P through V - which address topics such as personal ethics, character, and traditional Islamic Sufism, and include famous classical texts such as Al-Ghazzali's Ihya’ ʿulum al-din and Nawawi's Riyadh as-Saaliheen.

Certain sections of the book were left untranslated (although the original Arabic text is retained), as Keller considered them irrelevant to modern societies.
