Of all acts of worship in Islam, Salah (prayer) is the most important. No one is a Muslim unless he performs it. No one can escape Hell if he does not perform it. The prayer is the first criterion on which a person faces trial in the Hereafter. It is indeed the main pillar of the Islamic edifice. This book is meant to be useful to anyone who wishes to understand the prayer in a simple form. The Malayalam original, first published in 1968, has already run to 34 editions - an indication of the immense popularity of this short book. The text of a few surahs have been appended at the end (along with their meaning) on the request of readers.
