Bismillah Walhamdulillah Was Salaatu Was Salaam ‘ala Rasulillah
Narrated Salman bin ‘Amir Ad-Dabbi (Radi-Allahu ‘anhu):
I heard Allah’s Apostle (Sallallahu ‘Alaihi Wa Sallam) saying, “Aqiqa is to be offered for a (newly born) boy, so slaughter (an animal) for him, and relieve him of his suffering.”
(Note: It has been quoted in Fateh-AL-Bari that the majority of the Religious Scholars agrees to the Hadith narrated in Sahih At-TlRMlZY that the Prophet (Sallallahu ‘Alaihi Wa Sallam) was asked about Aqiqa and he ordered 2 sheep for a boy and one sheep for a girl and that is his tradition “SUNNA”.)
