This is one of the short treatises written by the great scholar and Imam Allama Jalaluddin al-Suyuti (d. 911 AH), describing the right belief about the parents of Prophet Muhammad (peace be upon him), that they are indeed saved and in Jannah.
Some of the scholars in past have cast doubt over the belief of the parents of Prophet Muhammad (peace be upon him), that whether they were Muslims or not. This doubt is due to the fact that there was no established religion before the Prophethood of Prophet Muhammad. Some of the Hadiths also point to the fact that they were not Muslims. But this is only a minority view in the scholars of Ahl as-Sunnah. Even those who do not believe that they were Muslims, keep silent over this issue rather than saying clearly that they were Non-Muslims and are in Hell.
Imam Suyuti authored multiple short books upon this issue. These books are specially important today, as some people from the new sect of Wahhabism are openly declaring the blessed parents of the Prophet as being in Hell, a clear blasphemy against the Final Messenger of Allah (peace be upon him). May Allah give peace and mercy to Imam Suyuti who has already cleared the issue by proving from the Quran and Sunnah that the blessed parents were indeed Muslim and righteous believers, and even were resurrected after death to make a belief in Prophet Muhammad (peace be upon him).
