I chose this from my humble Islam section in my home collection, to accompany my travels in Oman. It's basically an awkwardly cobbled together, huddiedly edited instruction manual for Islamic prayer and worship. It is the most in-depth book I have read as far as detailing the steps and minute rules of Islamic rituals, both in and outside the mosque. Useful, I'm sure, for a practicing Muslim who has newly converted, but not the most engaging reading material for the curious non-Muslim who merely wants to gain a deeper insight into the religion and its practices. Much of the heavy detail, worsened by the repetition and poor editing, wore on my patience a bit as I was not planning on actually implementing the steps for making dua, performing wudu or ghusl, and such things. It largely just went through one synapse and out the other, so to speak.
But still, I did learn a lot of new things about Islam, and I liked the abridged (i.e. less brutally honest) biography of the Prophet (salla allahu alayhi wa sallam - which honestly, in accompaniment with my learning Arabic, I absolutely love to say. It rolls so well off the tongue).
