Does the Hadith "Upon every household each year is an Uḍḥiyah and an ‘Atīrah" indicate the Sunnah of slaughtering an animal in Rajab (the ‘Atīrah)?

Scholars have differed concerning the ruling on the Atirah. The Shafii school holds that it is desirable (mustahabb), while the majority consider it abrogated. Some scholars have reconciled the narrations regarding the Atirah by interpreting the negating hadiths as negating obligation (wujub), not legality (mashruiyah) or desirability (istihbab).
