Narrated Samurah: That the Messenger of Allah said: "The boy is mortgaged by his 'Aqiqah; slaughtering should be done for him on the seventh day, he should be given a name, and his head should be shaved."
حَدَّثَنَا عَلِيُّ بْنُ حُجْرٍ، أَخْبَرَنَا عَلِيُّ بْنُ مُسْهِرٍ، عَنْ إِسْمَاعِيلَ بْنِ مُسْلِمٍ، عَنِ الْحَسَنِ، عَنْ سَمُرَةَ، قَالَ قَالَ رَسُولُ اللَّهِ صلى الله عليه وسلم " الْغُلاَمُ مُرْتَهَنٌ بِعَقِيقَتِهِ يُذْبَحُ عَنْهُ يَوْمَ السَّابِعِ وَيُسَمَّى وَيُحْلَقُ رَأْسُهُ " .
