Sayyiduna Abdullah bin Umar (may Allah be pleased with them both) met one of his relatives whose name was Mujbir (he was the nephew of Sayyiduna Abdullah bin Umar, the son of Sayyiduna Abdur Rahman bin Umar, may Allah be pleased with them both). He had performed the Tawaf al-Ifadah but, out of ignorance, had neither shaved his head nor shortened his hair. So Sayyiduna Abdullah bin Umar (may Allah be pleased with them both) instructed him to return, shave or shorten his hair, and then repeat the Tawaf az-Ziyarah.
