Translation of the verse 18 from Surah Yusuf : Number of verses 111 - - page 237 - Part 12.
And they brought his shirt stained with false blood. He said: "Nay, but your ownselves have made up a tale. So (for me) patience is most fitting. And it is Allah (Alone) Whose help can be sought against that which you assert."
And they brought upon his shirt false blood. [Jacob] said, "Rather, your souls have enticed you to something, so patience is most fitting. And Allah is the one sought for help against that which you describe."
(12:18) And (in proof thereof) they had brought his shirt with the false blood upon it. Hearing this, the father said, "No! your evil souls have made this heinous act easy for you. I, however, will bear this patiently with a good grace. *13 And Allah alone can be asked for help regarding what you are concocting. " *14
*13) The literal meaning of "good patience" which implies a patience that enables one to endure all kinds of troubles and afflictions in a calm, self-possessed and unrepining manner, without complaining or crying or weeping, as is worthy of great minds.
*14) Prophet Jacob's reaction to the news of Joseph's death, as depicted in the Qur'an, is also different from that given in the Bible and the Talmud. According to them he was upset by the sad news and behaved like an ordinary father. The Bible says, "And Jacob rent his clothes, and put sackcloth upon his loins. And mourned for his son many days." (Gen. 37: 34). And the Talmud says that at the sad news Jacob gave himself up to the abandonment of grief, and lay with his face to the ground.... and refused to be comforted, and cried, 'Some wild beast has devoured Joseph and I shall never see him more'; and he mourned for Joseph for many years. (The Talmud, H. Polano, pp. 78, 79).
When we contrast this picture with the one depicted in the Qur'an, we clearly see that the Qur'anic picture is that of a dignified and great personality. He is not upset in the least at hearing the sad news of his beloved son but at once gets to the bottom of the matter, and tells the envious brothers, "Your tale is false and fabricated." Then he shows "good patience" as a Prophet should and puts his trust in the help of God.
