"We were standing with the Prophet ﷺ at 'Arafat when I heard him say: 'O you people! For every household each year is Udhiyah (sacrifice) and 'Atirah. Do you know what an 'Atirah is ? It is that which you call Ar-Rajabiyyah.'" (Using translation from Tirmidhī 1518)
كُنَّا وُقُوفًا مَعَ النَّبِيِّ ﷺ بِعَرَفَاتٍ فَسَمِعْتُهُ يَقُولُ يَا أَيُّهَا النَّاسُ عَلَى كُلِّ أَهْلِ بَيْتٍ فِي كُلِّ عَامٍ أُضْحِيَّةٌ وَعَتِيرَةٌ هَلْ تَدْرِي مَا الْعَتِيرَةُ؟ هِيَ الَّتِي تُسَمَّى الرَّجَبِيَّةَ
