Greeting parents affectionately and making dua for them

Abu Hazim reported that Abu Murra, the mawla of Umm Hani' bint Abi Talib had told him that he rode with Abu Hurayra to his land in al-'Aqiq. When he entered his land, he shouted out in his loudest voice, "Peace be upon you, mother, and the mercy of Allah and His blessing!" She replied, "And peace be upon you and the mercy of Allah and His blessing." He said, "May Allah have mercy on you as you raised me when I was a child." She replied, "My son, may Allah repay you well and be pleased with you as you were dutiful towards me when I was old."  

أَنَّهُ رَكِبَ مَعَ أَبِي هُرَيْرَةَ إِلَى أَرْضِهِ بِالْعَقِيقِ فَإِذَا دَخَلَ أَرْضَهُ صَاحَ بِأَعْلَى صَوْتِهِ: عَلَيْكِ السَّلاَمُ وَرَحْمَةُ اللهِ وَبَرَكَاتُهُ يَا أُمَّتَاهُ تَقُولُ: وَعَلَيْكَ السَّلاَمُ وَرَحْمَةُ اللهِ وَبَرَكَاتُهُ, يَقُولُ: رَحِمَكِ اللَّهُ رَبَّيْتِنِي صَغِيرًا فَتَقُولُ: يَا بُنَيَّ وَأَنْتَ فَجَزَاكَ اللَّهُ خَيْرًا وَرَضِيَ عَنْكَ كَمَا بَرَرْتَنِي كَبِيرًا
