This book is a compilation of Forty Hadīths on the auspicious months of Rajab and Sha‘bān. These two months along with the Holy month of Ramadān form the season of worship. It is hoped that the Hadiths in this book will remind Mu’minīn of the sanctity of these months and inspire them to perform the ‘Ibādāt (acts of worships) recommended by the Ma‘sūmīn.
