The book Mansik by Shaykh al-Islam Ibn Taymiyyah, in which he explained the nature of Hajj and Umrah and the rulings of the visit, deals with several topics in a simplified narrative without linguistic complexities, such as the rule of the Meccan Umrah and what to say if one wants to perform Ihram. 

The book deals with the e-learning system via networks, the definition of this system, its tools, its ready-made applications, its institutions, and the utilization of teaching and learning resources and information sources that support the richness and effectiveness of this system in providing masterful distance education, whether in providing educational content, evaluation processes and electronic tests, and preparing the teacher to meet these needs and requirements of the system.
