Is the kurban animal required to be 2 years old?
The answer will be seen in the following hadith.
From Jabir radhiyallahu 'anhu, he said, Rasulullah sallallahu' alaihi wa sallam said,
"لَا تَذْبَحُوا إِلَّا مُسِنَّةً, إِلَّا أَنْ يَعْسُرَ عَلَيْكُمْ فَتَذْبَحُوا جَذَعَةً مِنَ اَلضَّأْنِ"
"Do not you slaughter unless it is Musinnah. Unless it is difficult for you, then slaughter jadza'ah from the sheep. " (HR. Muslim no. 1963)
Musinnah of goats is one year old (entering the second year). Meanwhile, cows are those who are already two years old (entering their third year). Meanwhile, camels are those who have completed five years (entering their sixth year). This was a popular opinion among the fuqoha.
Jadza'ah are sheep that are six to one year old.
In summary, the age requirements for sacrificial animals are presented in the following table:
