Musnad Ahmad Hadith 4631

It is narrated from Ibn Umar (may Allah be pleased with them both) that when Ghaylan bin Salamah Thaqafi accepted Islam, he had ten wives in his marriage. The Prophet Muhammad (ﷺ) said to him, "Select four from them (and release the rest)." So he did so. And when the caliphate of Umar (may Allah be pleased with him) came, he divorced his remaining wives as well and distributed all his wealth among his sons. Umar (may Allah be pleased with him) came to know of this and said, "I think Satan has come to know of your impending death by secretly listening and has put this thought into your heart. It may be that you will live only a short while now. By Allah! Either you return to your wives and also revoke your distribution of inheritance, or else I will make your wives heirs on your behalf (and will give them their share), and I will order stones to be thrown at your grave, just as stones are thrown at the grave of Abu Righal, so will they be thrown at your grave."
