The Brothers Approach Jacob
Their next movement opened the scene between them and their father Jacob : They said. "0 our father! Why do you not trust us with Joseph, when we are indeed his well-wishers? Send him with us tomorrow to enjoy himself and play, and verily, we will take care of him."
He (Jacob) said: "Truly, it saddens me that you should take him away. I fear lest a wolf should devour him, while you are careless of him."
They said: "If a wolf devours him, while we are Usbah (a strong group) (to guard him), then surely, we are the losers. " Surah 12: 11-14
Jacob suggested a point which had not occurred to them in their discussion: he feared that desert wolves would eat him! Did he imply the wolves within them, or did he mean the wild wolves? No one but Allah knows. They coaxed their father to send Joseph with them; he agreed under their pressure.

Joseph Thrown into the Well
They were excited that they could now get rid of Joseph for after this they could stand a better chance of receiving their father's affection. On leaving home, they went directly to the well, as they had planned, on the pretext of drinking water. One of them put his arms around Joseph and held him tightly. Startled by this unusual behavior, Joseph struggled to free himself. More brothers rushed to hold him. One of them removed his shirt. Some more joined in to lift Joseph up and cast him into the deep well. Joseph's piteous pleas made no difference to their cruel hearts.
Then Allah revealed to Joseph that he was safe and should not fear, for he would meet them again some day to remind them of what they had done.
There was water in the well which buoyed Joseph's body, so he was not harmed. He sat lonely in the water, then clung to a rock ledge overhead and climbed on top of it. His brothers left him in this desolate place. Then they killed a sheep and soaked Joseph's shirt in its blood. One brother said that they should swear to keep their deed a close secret. All of them took the oath.

The Brothers Lie to Jacob
And they came to their father in the early part of the night weeping. Surah 12: 16
The scene here is dark night, broken by the crying of ten men. The father is sitting in his house when the sons enter, the darkness of night covering the darkness of their hearts and the darkness of their lies struggling to come out. Jacob wondered aloud: "Why this weeping? Has anything happened to the flock?" They answered crying: "0 our father! We went racing with one another, and left Joseph by our belongings and a wolf devoured him; but you will never believe us even when we speak the truth. Surah 12: 17
"We were surprised after returning from the race that Joseph was in the belly of the wolf."
"We did not see him!"
'You will not believe us even though we are truthful, but we are telling you what happened!"
"The wolf has eaten Joseph!"
"This is Joseph's shirt. We found it soiled with blood, and did not find Joseph!"
And they brought his shirt stained with false blood. Surah 12: 18
Deep down in his heart Jacob knew that his beloved son was still alive and that his other sons were lying. He held the blood-stained shirt in his hands, spread it out and remarked: "What a merciful wolf! He ate up my beloved son without tearing his shirt!" Their faces turned red when he demanded more information, but each one swore by Allah that he was telling the truth. The broken hearted father burst into tears: "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. " Surah 12: 18
The father acted wisely by praying for mighty patience which is free of doubt and by trusting in Allah for help against what they had plotted against him and his son. This scene dims, and the scene opens in the well with which Joseph had been thrown.
