Allah, the Almighty told us: They said: "By Allah! You will never cease remembering Joseph until you become weak with old age, or until you be of the dead."
He said. "I only complain of my grief and sorrow to Allah, and I know from Allah that which you know not. 0 my sons! Go you and enquire about Joseph and his brother, and never give up hope of Allah's Mercy. Certainly no one despairs of Allah's Mercy, except the people who disbelieve." Surah 12: 85-87
