عَنْ أَبِي مُوسَى قَالَ: قَالَ رَسُولُ اللَّهِ صَلَّى اللَّهُ عَلَيْهِ وَسَلَّمَ: «أَطْعِمُوا الْجَائِعَ وَعُودُوا الْمَرِيض وفكوا العاني» . رَوَاهُ البُخَارِيّ

‘A’isha said

When one of us had a complaint God’s messenger wiped him with his right hand and then said, “Remove the harm, Lord of men, and give healing. Thou art the Healer. There is no healing but Thine, a healing which leaves no illness behind.” (Bukharl and Muslim.)
