Yusuf - 12:85

قَالُواْ تَالله تَفْتَأُ تَذْكُرُ يُوسُفَ حَتَّى تَكُونَ حَرَضًا أَوْ تَكُونَ مِنَ الْهَالِكِينَ
[12:85]
They said: By Allah! you will not cease to remember Yusuf until you are a prey to constant disease or (until) you are of those who perish.
They said: "By Allah! (never) wilt thou cease to remember Joseph until thou reach the last extremity of illness, or until thou die!"
They said: By Allah, thou wilt never cease remembering Joseph till thy health is ruined or thou art of those who perish!
