Narrated Umar ibn as-Sa'ib: One day when the Messenger of Allah (ﷺ) was sitting, his foster-father came forward. He spread out of a part of his garment and he sit on it. Then his mother came forward to him and he spread out the other side of his garment and she sat on it. Again , his foster-brother came forward. The Messenger of Allah (ﷺ) stood for him and seated him before himself.
