It was narrated from Habib bin Ash-Shahid:

"Muhammad bin Sirin said to me: 'Ask Al-Hasan (Al-Basri) from whom he heard this Hadith about the 'Aqiqah.' I asked him about that and he said: 'I heard it from Samurh."'

أَخْبَرَنَا هَارُونُ بْنُ عَبْدِ اللَّهِ، قَالَ حَدَّثَنَا قُرَيْشُ بْنُ أَنَسٍ، عَنْ حَبِيبِ بْنِ الشَّهِيدِ، قَالَ لِي مُحَمَّدُ بْنُ سِيرِينَ سَلِ الْحَسَنَ مِمَّنْ سَمِعَ حَدِيثَهُ، فِي الْعَقِيقَةِ ‏.‏ فَسَأَلْتُهُ عَنْ ذَلِكَ، فَقَالَ سَمِعْتُهُ مِنْ، سَمُرَةَ ‏.‏
