In this book Imam Ibn Taymiyyah explains the obligations of the ruler and the ummah's responsibilities towards the Ruler. The shaykh explains the principles by which to select the best Ruler according to Shari'ah. The Book is based on an Extensive commentary of the following verses of Surah Nisah: 'Verily, Allah commands that you should render back the trusts to those, to whom they are due, and that when you judge between men, you judge with justice. Verily, how excellent is the teaching which He gives you! Truly, Allah is Ever All-Hearer, All-Seer. O you who believe! Obey Allah and obey the Messenger, and those charged with authority among you. If you differ in anything among yourselves, refer it to Allah and His Messenger, if you do believe in Allah and the Last Day: that is best, and most suitable for final determination.' TM Qur'an 4:58-59
