Shaykh Badr ibn Naadir al-Mashaaree narrates:
Despite the ill-health of the Shaykh, he was steadfast in delivering the Jumu’ah khutbah in al-Jaami’ al-Kabeer and leading the prayers and meeting the people to answer their questions and enquiries; All this in spite of what he was going through himself, such that it was said to him: “Rest yourself O Shaykh”, to which he replied: “Resting is in being at the service of the Muslims”.
