Abu Hurayrah & His Mother

Imaam Bukhari narrated in al Adab al Mufrad: 

Abee Murrah narrated that the Mawla of Umm Hani bint Abee Taalib had informed him that he rode with Abu Hurayrah to his land (al-Aqeeq). Whereupon he (Abu Hurayrah) entered his land, he shouted in his loudest voice, "May the peace, blessings and mercy of Allaah be upon you Oh mother," She replied, "and may the peace, blessings and the mercy of Allaah be upon you." He said, "May Allaah have mercy upon you as you nurtured me when I was young." She replied, "O my son, likewise to you! May Allaah reward you and be pleased with you as you were dutiful to me when I grew old."
