It is narrated from Abu Khasib, he says: I was sitting when Sayyiduna Abdullah bin Umar (may Allah be pleased with them) arrived. A man stood up from his gathering to give him space, but he did not sit in that place; rather, he sat somewhere else. That man said: If you had sat in my place, would there have been any harm upon you? He replied: Neither do I wish to sit in your seat nor in anyone else’s seat, after what I myself witnessed in the presence of the Messenger of Allah (peace and blessings be upon him). The detail is that a man came to the Messenger of Allah (peace and blessings be upon him), so another man stood up from his gathering for his sake, and he was about to sit in his place, but the Messenger of Allah (peace and blessings be upon him) forbade him from sitting there.
