What has been authentically narrated concerning the care for health and relief?

Health and relief fall under helping a Muslim and alleviating their distress, and this has a great reward known only to Allah. In the prophetic Hadith: "And whoever is in the need of his brother, Allah will be in his need. And whoever relieves a Muslim of a distress, Allah will relieve him of a distress from the distresses of the Day of Resurrection. And whoever shields a Muslim, Allah will shield him on the Day of Resurrection." In another Hadith: "Whoever removes a worldly distress from a believer, Allah will remove a distress from him on the Day of Resurrection. And whoever eases the burden of a debtor, Allah will ease his burden in this world and the Hereafter. And whoever shields a Muslim, Allah will shield him in this world and the Hereafter. And Allah is in the aid of His servant as long as the servant is in the aid of his brother."
