Silsilat al-Ahadith al-Sahihah

Abu Ubaidah bin Hudhaifah narrates from his aunt, Sayyidah Fatimah (may Allah be pleased with her), that she said: We went with a few women to tend to the Messenger of Allah (peace and blessings be upon him). There was a water-skin hanging above the Prophet (peace be upon him), and due to the heat of the fever, its drops were dripping onto him. We said: O Messenger of Allah! If you pray to Allah Almighty for healing, He will grant you healing. Upon hearing this, the Messenger of Allah (peace and blessings be upon him) said: "Among the people, the prophets are tested with the most severe trials, then those who are nearest to them in rank, then those who are nearest to them, then those who are nearest to them."
