This book by renowned scholar and recognised authority on Islam, Shaykh-ul-Islam Dr Muhammad Tahir-ul-Qadri, is a discourse on the legal position of celebrating the Mawlid al-Nabi (birthday of the Prophet Muhammad (PBUH)) within Islam. Most notably, the author has comprehensively compiled evidences from the authentic source texts and classical authorities to prove not only the permissibility of celebrating the Mawlid al-Nabi within the bounds of the Shari'a (Islamic Law) but also that it is divinely ordained and was a Sunna (practice) of the Prophet himself. The author presents unique and compelling arguments showing why celebrating Mawlid al-Nabi is not only an act of righteousness, but a need of our time. Tackling the various criticisms of this act head on, he specifically addresses the issue of why the first generation of Muslims did not celebrate the Mawlid, and clarifies that labelling the Mawlid as an bid'ah (innovation) betrays a fundamental and serious flaw in the understand of the Islamic concept of bid'ah.
