Abdullah ibn Rafi’ reported: I said to Abu Huraira, may Allah be pleased with him, “Why were you nicknamed Abu Huraira?” Abu Huraira said, “I would tend to the sheep of my people and I had a small kitten. I used to place it in a tree at night and during the day I would take it and play with it. So they nicknamed me Abu Huraira, ‘father of the kitten.’”

عَنْ عَبْدِ اللَّهِ بْنِ رَافِعٍ قَالَ قُلْتُ لِأَبِي هُرَيْرَةَ رضي الله عنه لِمَ كُنِّيتَ أَبَا هُرَيْرَةَ قَالَ كُنْتُ أَرْعَى غَنَمَ أَهْلِي وَكَانَتْ لِي هُرَيْرَةٌ صَغِيرَةٌ فَكُنْتُ أَضَعُهَا بِاللَّيْلِ فِي شَجَرَةٍ فَإِذَا كَانَ النَّهَارُ ذَهَبْتُ بِهَا مَعِي فَلَعِبْتُ بِهَا فَكَنَّوْنِي أَبَا هُرَيْرَةَ
