Mishkat al-Masabih 20 Game and Animals Which May Be Slaughtered كتاب الصيد والذبائح 84

عَن سلمانَ بن عامرٍ الضَّبي قَالَ: سَمِعْتُ رَسُولَ اللَّهِ صَلَّى اللَّهُ عَلَيْهِ وَسَلَّمَ يَقُولُ: «مَعَ الْغُلَامِ عَقِيقَةٌ فَأَهْرِيقُوا عَنْهُ دَمًا وأمِيطوا عَنهُ الْأَذَى» . رَوَاهُ البُخَارِيّ

Salman b. ‘Amir ad Dabbl told that he heard God’s messenger say, “Along with a boy there is an ‘aqiqa , so shed blood on his behalf and remove injury from him.”* *This is variously explained as shaving the hair of the infant, or removing the impurities with which it is defiled at birth, or even circumcision. Bukhari transmitted it.
