It was narrated from `Imran bin Hittan, according to what Harb thinks, who asked Ibn `Abbas about silk garments. He said:
Ask `A`ishah about that. So he asked `A`ishah and she said: Ask Ibn `Umar (...). So he asked Ibn `Umar, and he said: Abu Hafs told me that the Messenger of Allah (ﷺ) said: `Whoever wears silk in this world will have no share of it in the Hereafter.”
