The book "Ruhul Adab" is a collection of verses from the Quran, the Sunnah, and the teachings of the Prophet (SAWS) and his companions.

The book contains a one hundred and twenty-one-verse poem in praise of Allah (God), glorified is He, and in commemoration of His Holy Prophet Muhammad (SAWS), named "Spirit of Good Morals". It was written by Shaykh of Islam Al-Hajj Ibrahim ibn Al-Hajj Abdullah Niasse, as advice to the "People of Tariqa", the Tijaniyya Brotherhood in particular, and to humanity at large.

Since that time it has been translated into English by his grandson Shaykh Hassan ‘Aliyyu Cisse, the Chief Imam of Shaykh Ibrahim Niasse Mosque (pictured on the front). Most recently, Shaykh Hassan Cisse has added verses from Al-Quran, narrations of the Prophet (SAWS), and his own commentary which relate to the poetic verses of the advice.
