The cure for Death!!
A man once asked Ka'b, "Which illness cannot be treated?" "Death", he replied. The son of Zayd b. Aslam [d136H] said: My father said, "There is one treatment for death: gaining the pleasure of Allah 'azza wa jall." Ibn Abī Al-Dunyā in Dhikr Al-Mawt no. 418 Advice from Abu Al-Darda'
A man once asked Abū Al-Dardā' Allah be pleased with him for advice. He said: Remember Allah in good times and He will mention you in hard times. When you remember those who have passed away, consider yourself like one of them. And when you think of involving yourself in some worldly matter, consider first what it will lead to in the end. Al-Dhahabī in Siyar A'lām Al-Nubalā', under the biography of Abū Al-Dardā'.
