Silsilat al-Ahadith al-Sahihah

Sayyiduna Abu Ubaidah bin Hudhaifah narrates from his paternal aunt Sayyidah Fatimah (may Allah be pleased with her) that she said: We, a few women, went to tend to the Messenger of Allah (peace and blessings be upon him). A water-skin was hanging above the Prophet (peace and blessings 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 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 the most severely, then those who are nearest to them in rank, then those who are nearest to them, then those who are nearest to them."
