عَنْ سَمُرَةَ رَضِيَ اللَّهُ عَنْهُ أَنَّ رَسُولَ اللَّهِ صَلَّى اللَّهُ عَلَيْهِ وَآلِهِ وَسَلَّمَ قَالَ كُلُّ غُلَامٍ رَهِينٌ بِعَقِيقَتِهِ تُذْبَحُ عَنْهُ يَوْمَ السَّابِعِ وَيُحْلَقُ رَأْسُهُ وَيُسَمَّى
Narrated from Sayyiduna Samurah (may Allah be pleased with him) that the Messenger of Allah (peace and blessings be upon him) said: Every child is held in pledge for his 'aqiqah; on the seventh day, an animal should be sacrificed on his behalf, his head should be shaved, and he should be named.
