Ishmael Shoots an Arrow at Isaac and Sarah Demands His Removal

Yalkut Shimoni on Torah 94:3

The ninth trial: Ishmael was born and grew up skilled with the bow, as it is said, "And God was with the lad" and so on. He took a bow and arrows and would shoot from behind the curtain, and he saw Isaac sitting alone and shot an arrow at him to kill him. Sarah saw and told Abraham, saying to him: Thus and so did Ishmael do to Isaac. Arise and write for Isaac all that the Holy One, blessed be He, swore to give to you and to your seed, for the son of this maidservant shall not inherit together with my son Isaac. Sarah said: Write a bill of divorce, send away this maidservant and her son from me and from Isaac my son, from this world and from the world to come. And of all the evils that came upon Abraham, this matter was evil in his eyes.
