He feared that Allah would reveal to the prophet pbuh evidence of his hypocrisy. His guilt denied him to ever show his face to the prophet pbuh. So he ran away. Days went by and the prophet kept asking the other companions if they had seen Thalaba. No one had seen him. With the prophet's worry about Thalaba he sent a few of the companions to look for him everywhere, among them were Omar Ibn Al Khattab and Salman Al Farisiy. They looked everywhere in Medina, and on the out skirts of Madina, until they came about a set of mountains between Mecca and Medina where some nomads were herding sheep. The companions asked the nomads if they had seen a young man with Thalaba's characteristics. They told the companions about a weeping boy. He had been here for 40 days. He came down from the mountains once a day weeping and drank the milk they would offer him. Then he went back up the mountains weeping, crying, always asking for Allah for forgiveness, and saying words of repentance. So the companions waited until he came down and watched him. He had lost weight. His countenance reflected sorrow as he drank the milk that was mixed with his tears.
The companions insisted that they take him back to the prophet pbuh but he refused and asked them if Allah had revealed verses saying he was a hypocrite. They told him that they had no knowledge of any such verses. He was taken back to Medina where the prophet pbuh went to see him. He asked again if Allah had put him among the hypocrites or revealed that he was. The prophet pbuh assured him that there were no such verses. He laid out Thalaba's tired, weak body and placed Thalaba's head on his lap. He said, "Oh prophet of Allah remove the head of a sinner away from you." The prophet pbuh comforted him until he told the prophet pbuh I feel as though ants are walking between my flesh and bones. The prophet told him it was death and his time had come. He witnessed while Thalaba's head was on his lap, Thalaba proclaimed. "There is no god worthy of worship other than Allah, and that Mohammad pbuh is the messenger of Allah." The prophet pbuh washed Thalaba and carried him to the grave. It is narrated that on their way to bury Thalaba, the prophet pbuh walked on his tippy toes as though he were in a crowd. When Umar asked about this, the prophet pbuh explained that he was being crowded with the angels."
