Wudoo’: The Prophet’s Ablution is a small yet comprehensive book aimed at conveying authentic knowledge of the manner in which the Prophet (blessings and peace be upon him) purified himself for prayer. The attributes of the Prophet’s ablution are detailed fully, such that the reader is given a clear mental picture, as if we were witnessing the Prophet actually making wudoo’. This book is based on sound narrations from the Messenger of Allah (blessings and peace be upon him), and the author takes care to include differing opinions and their evidence.
From leading us through the wudoo’ step by step, to addressing the things which nullify the wudoo’, The Prophet’s Ablution offers necessary guidance, so that by perfecting our ablution, this purification can truly «wipe away the sins.»
Another great book to read of one of the basic requirements for the greatest pillar of Islam, the Salah (prayer).
The greatest benefit I learnt from this book was that the order of washing in Wudu' is not restricted to what we are normally accustomed to, the narration is as follows:
Al-Midam ibn Ma'dikarb said: I came to the Prophet (ﷺ) with water for wudu', so he washed his hands three times, then washed his face three times, then washed his forearms three times, then he washed his mouth and nose three times, then wiped his head and ears --- their insides and outsides and washed each of his feet three times.
[Ahmad, vol.4, p.132; Abu Dawood, vol.1, p.19. The narration is saheeh]
I suggest people who are concerned about whether or not their Salah is accepted should of course learn about the conditions for which it becomes valid. Wudu' is one of the greatest and thus it is essential one learns about it.
