Narrated Abu Musa:

I got a son and I took him to the Prophet (ﷺ) who named him Ibrahim, and put in his mouth the juice of a date fruit (which be himself had chewed?, and invoked for Allah's blessing upon him, and then gave him back to me. He was the eldest son of Abii Musa.

حَدَّثَنَا مُحَمَّدُ بْنُ الْعَلاَءِ، حَدَّثَنَا أَبُو أُسَامَةَ، عَنْ بُرَيْدِ بْنِ عَبْدِ اللَّهِ بْنِ أَبِي بُرْدَةَ، عَنْ أَبِي بُرْدَةَ، عَنْ أَبِي مُوسَى، قَالَ وُلِدَ لِي غُلاَمٌ، فَأَتَيْتُ بِهِ النَّبِيَّ صلى الله عليه وسلم فَسَمَّاهُ إِبْرَاهِيمَ، فَحَنَّكَهُ بِتَمْرَةٍ، وَدَعَا لَهُ بِالْبَرَكَةِ، وَدَفَعَهُ إِلَىَّ، وَكَانَ أَكْبَرَ وَلَدِ أَبِي مُوسَى‏.‏
