Syedna Abu Saeed Khudri (may Allah be pleased with him) narrates that the Messenger of Allah (peace and blessings be upon him) forbade fasting on two days, performing two prayers, and two types of marriages. The details are as follows: He (peace and blessings be upon him) forbade performing prayer after the Fajr prayer until sunrise and after the Asr prayer until sunset, fasting on the days of Eid al-Fitr and Eid al-Adha, and combining a woman and her maternal aunt or a woman and her paternal aunt in one marriage.
