In the parable of the prodigal son, which son asked for his share of the estate?

Answer: The younger son

The younger son asked for his share, then went to a distant country and squandered it in wild living.

“Then Jesus said, “There was a man who had two sons. The younger son said to him, ‘Father, give me my share of the estate.’ So he divided his property between them. After a few days, the younger son got everything together and journeyed to a distant country, where he squandered his wealth in wild living.”— Luke 15:11-13 (BSB)
