Goliath turned to David and said, “Go back, for I have no wish to kill you.” David replied, “But I very much wish to kill you!” He took the three stones, placed them in his sling, whirled it until the three fused into a single stone, and cast it at Goliath, splitting his head open. Goliath’s army fled in panic.
Saul then fulfilled his pledge: he married David to his daughter and allowed him to exercise authority in his kingdom. David (peace be upon him) grew great in the eyes of the Children of Israel; they loved him and inclined toward him more than toward Saul. It is reported that Saul envied him and intended to kill him, devising stratagems but never managing to reach him. The scholars forbade Saul to kill David, so he turned on them and slew them until only a few remained.
Later repentance was granted to Saul: remorse seized him and he renounced what he had done. He wept profusely and would go out to the graveyard, crying until the earth was soaked with his tears. One day a voice called out to him from the cemetery: “O Saul, you killed us while we were alive and have harmed us now that we are dead!” His weeping, fear, and dread increased. He began seeking a learned person who could tell him whether any repentance remained open to him.
People said to him, “Have you left any scholar alive?” Eventually he was directed to a devout woman, who took him to the grave of Joshua (peace be upon him). They say she supplicated Allah, whereupon Joshua rose from his grave and said, “Has the Hour been established?” She replied, “No, but this is Saul asking whether repentance is possible for him.” Joshua said, “Yes: he must relinquish the kingdom, go forth, and fight in the cause of Allah until he is killed.” Joshua then returned to death.
Saul therefore gave the kingship to David (peace be upon him) and departed with thirteen of his sons. They fought in the cause of Allah until they were slain. They said that this is the meaning of His words: “And Allah granted him the kingdom and wisdom and taught him of what He willed” (2:251).
Thus Ibn Jarīr related it in his History (1) through al-Suddi’s chain. Some parts of it (2) warrant scrutiny and objection; Allah knows best.
Muḥammad ibn Isḥāq said: The prophet who was sent and informed Saul of his repentance was Elisha ibn Akhṭūb; Ibn Jarīr (3) also transmitted this. Al-Thaʿlabī reports that she brought him to the grave of Samuel, who reproached him for what he had done after Samuel’s death—this account is more fitting. It is likely that Saul only saw him in a dream rather than that he actually rose alive from the grave, for such an occurrence would be a miracle reserved for a prophet, and the woman was not a prophetess. Allah knows best.
Ibn Jarīr (4) also said: The people of the Torah claim that the duration of Saul’s reign until he was killed along with his sons was (5) forty years. Allah knows best.
