Silsilat al-Ahadith al-Sahihah

Sayyiduna Abu Sa'id Khudri (may Allah be pleased with him) says: I went to the Prophet (peace and blessings of Allah be upon him), he was suffering from severe fever. I placed my hand on him over the blanket and felt the heat. I said: O Messenger of Allah! You have such a severe fever! The Prophet (peace and blessings of Allah be upon him) said: "For us, where the trial is doubled, the reward is also doubled." I said: O Messenger of Allah! Upon whom is the trial the hardest? The Prophet (peace and blessings of Allah be upon him) said: "The Prophets, and then the righteous people after them. Sometimes, such severe trials of worry and hunger befall them that they possess nothing except a single cloak to cover their bodies, but these people are as happy with trials and tests as people are happy with ease and prosperity."
