Praying 'Eid in the Musallaa is the Sunnah: there is great and profound wisdom behind this Sunnah – the Sunnah of praying in an open area of land. And it is that: The Muslims will have two days of the year where all the people of every city can gather together – whether men, women or children - and turn towards Allaah with their hearts in unity, praying behind one Imaam, making the Takbeer, the Tahleel and supplicating to Allaah sincerely together, as if they were united upon the heart of one man, happy and joyous about the blessing Allaah has bestowed on them. So the Eid will truly be an occasion of celebration for them.

This is a useful book although it is small. It contains some technical terms for da'wah in English. No doubt all scholars and callers to Islam in English are in much need to something like that to conveys the right message of Islam to all those speak English.
Translated from the original Arabic into English, provides a vivid insight into the moral conduct of the early Muslims in a society led by the perfect character of the Prophet Muhammad (pbuh) ('I was only sent to perfect good character'). The Prophet's Companions represent excellent examples of men of vigorous moral stature whose conduct inspired and attracted the masses to the fold of Islam wherever they went during the expansion of the Muslim territories, and contrary to the stereotypic portrayal, in the West, of Islam as being spread by the sword.
