A very important book talks about some misconceptions about Islam such as: allowing husbands to beat their wives, punishments by Islam for the criminals, not allowing religious freedom which is considered intolerance, prohibiting music, and terrorism in the name of jihad.
My brother pilgrim, as there is for every group a leader and for every journey a guide, the leader of the Hajj group is the prophet Muhammad (peace be upon him) and their guide is his example and Sunnah, for he has said “ take from me your rites of Hajj”. Therefore it's incumbent on everyone who approaches the House of Allah for hajj or Umrah to learn the way it was performed by the prophet (peace be upon him) through accurate guide books and by asking scholars about any uncertainties one may have. This book is written in clear language and has a new format which presents and simplifies for you the rulings pertaining to Hajj and Umrah which I hope you will make use of as your guide.
