What are the three things that the Prophet, may Allah’s prayers and peace be upon him, mentioned are acts of Jahiliyyah (pre-Islamic ignorance) and that the people of Islam will not abandon?

Muslim narrated from Abu Malik Al-Ash'ari that the Prophet, peace and blessings be upon him, said: "Four matters from the affairs of Jahiliyyah (pre-Islamic ignorance) will remain in my Ummah, which they will not abandon: boasting about ancestry, slandering genealogies, seeking rain through stars, and wailing over the dead. And the wailing woman, if she does not repent before her death, will be raised on the Day of Resurrection wearing a garment of tar and a shield of scabs."
