Sahih Bukhari Volume 8, Book 78, Hadith 5973

حَدَّثَنَا قُتَيْبَةُ بْنُ سَعِيدٍ، حَدَّثَنَا جَرِيرٌ، عَنْ عُمَارَةَ بْنِ الْقَعْقَاعِ بْنِ شُبْرُمَةَ، عَنْ أَبِي زُرْعَةَ، عَنْ أَبِي هُرَيْرَةَ ـ رضى الله عنه ـ قَالَ جَاءَ رَجُلٌ إِلَى رَسُولِ اللَّهِ صلى الله عليه وسلم فَقَالَ يَا رَسُولَ اللَّهِ مَنْ أَحَقُّ بِحُسْنِ صَحَابَتِي قَالَ ‏"‏ أُمُّكَ ‏"‏‏.‏ قَالَ ثُمَّ مَنْ قَالَ ‏"‏ أُمُّكَ ‏"‏‏.‏ قَالَ ثُمَّ مَنْ قَالَ ‏"‏ أُمُّكَ ‏"‏‏.‏ قَالَ ثُمَّ مَنْ قَالَ ‏"‏ ثُمَّ أَبُوكَ ‏"‏‏.‏ وَقَالَ ابْنُ شُبْرُمَةَ وَيَحْيَى بْنُ أَيُّوبَ حَدَّثَنَا أَبُو زُرْعَةَ مِثْلَهُ‏.

Narrated By Abu Huraira : A man came to Allah's Apostle and said, "O Allah's Apostle! Who is more entitled to be treated with the best companionship by me?" The Prophet said, "Your mother." The man said. "Who is next?" The Prophet said, "Your mother." The man further said, "Who is next?" The Prophet said, "Your mother." The man asked for the fourth time, "Who is next?" The Prophet said, "Your father."
