Narrated from Sayyiduna Abdullah bin Mas’ud (may Allah be pleased with him), he says: I was walking with the Noble Prophet (peace and blessings be upon him) in a field of Madinah, while he (peace and blessings be upon him) was leaning on a twig. Meanwhile, the Prophet (peace and blessings be upon him) passed by a group of Jews. They said to one another: Ask him about the soul. Some said: Do not ask him anything. But then they asked and said: O Muhammad! What is the soul? The Prophet (peace and blessings be upon him) stood up leaning on the twig. I thought that revelation was being sent down upon him. Then the Prophet (peace and blessings be upon him) recited this verse: {وَیَسْأَ لُونَکَ عَنِ الرُّوحِ قُلِ الرُّوحُ مِنْ أَ مْرِ رَبِّی وَمَا أُوتِیتُمْ مِنَ الْعِلْمِ إِلَّا قَلِیلًا} … They ask you concerning the soul. Say: The soul is by the command of my Lord, and you have been given only a little knowledge. Then some of them began to say to others: Did we not tell you not to ask him?
