Hadith: Whoever can afford it but does not offer a sacrifice, let him not come near our prayer place

عن أبي هريرة، أن رسول الله صلى الله عليه وسلم قال: «مَن كان له سَعَة، ولمْ يُضَحِّ، فلا يَقْرَبَنّ مُصَلّانا».
[حسن] - [رواه ابن ماجه وأحمد]

Abu Hurayrah (may Allah be pleased with him) reported that the Prophet (may Allah's peace and blessings be upon him) said: "Whoever can afford it but does not offer a sacrifice, let him not come near our prayer place."
[Good hadith] - [Narrated by Ibn Majah - Narrated by Ahmad]

Explanation

Abu Hurayrah (may Allah be pleased with him) reports that the Prophet (may Allah's peace and blessings be upon him) said that any Muslim who is financially capable of offering a sacrificial animal on the Day of Eid al-Ad'ha, but does not do so, let him not approach the Eid prayer place of Muslims nor pray with the people, because the Muslim should not neglect this ritual while he is able to offer it. Offering the sacrificial animal is a great act of worship and a rite that should be observed on the day of Eid al-Ad'ha. The majority of scholars said that it is a confirmed act of Sunnah. Some scholars said that it is obligatory on those who are financially capable.
