Ibrahim (may Allah have mercy on him) said that a free person should not be prevented from engaging in trade.

Hazrat Husain (may Allah have mercy on him) narrates that I was present with Hazrat Shurayh (may Allah have mercy on him) when a man came along with his nephew, against whom he was seeking help. The man submitted that his nephew consumes a lot of intoxicating substances (he was referring to alcohol). Hazrat Shurayh (may Allah have mercy on him) said, "Stop giving him pocket money and spend on him in a good manner." Hazrat Husain (may Allah have mercy on him) states that the nephew had already grown a beard.

It is narrated from Hazrat Abdul Malik bin Mughirah, may Allah have mercy on him, that Najdah wrote to Hazrat Ibn Abbas, may Allah be pleased with them both, and inquired about the ruling regarding an old man whose intellect has vanished or who has become unintelligent. He, may Allah be pleased with him, wrote to him that when his intellect vanishes or he becomes unintelligent, he should be prevented from trade and similar activities.

It is narrated in a similar manner from Hazrat Ibn Abbas (may Allah be pleased with them both).
