Prophet Musa (a.s.) was quite surprised and went to search for that butcher. He saw that the butcher was busy selling meat in his shop. At his day end he wrapped a piece of meat in clothe and returned home. To find out more about his house he pretended to be his guest for the night and the butcher readily accepted.
After reaching home he cooked the meat baked some bread and soaked the bread in the dish and went into a room where an extremely old lady was laying on the bed. With much effort he raised the old women from the bed and gave her food bite by bite. When he had finished serving the food he wiped her face. The old woman then said something in the butcher’s ears which made him to smile and laid her back on the bed and came out of the room.
Prophet Musa who was watching all this, asked the butcher, “who is this lady and what did she say in your ears that brought a smile on your face?”
The butcher replied, “O stranger, she is my mother. The first thing I do after returning home is to serve her. She gets pleased everyday and prays that may Allah make me the neighbor of Prophet Musa in Jannah, and on this I smile, look at my status and the status of Musa Kaleem ul Allah."
We Read in Surah Al-Israa, Ayah Number 23-24,
وَقَضَى رَبُّكَ أَلاَّ تَعْبُدُواْ إِلاَّ إِيَّاهُ وَبِالْوَالِدَيْنِ إِحْسَانًا إِمَّا يَبْلُغَنَّ عِندَكَ الْكِبَرَ أَحَدُهُمَا أَوْ كِلاَهُمَا فَلاَ تَقُل لَّهُمَا أُفٍّ وَلاَ تَنْهَرْهُمَا وَقُل لَّهُمَا قَوْلاً كَرِيمًا
And your Lord has commanded that you shall not serve (any) but Him, and goodness to your parents. If either or both of them reach old age with you, say not to them (so much as) "Ugh" nor chide them, and speak to them a generous word.
وَاخْفِضْ لَهُمَا جَنَاحَ الذُّلِّ مِنَ الرَّحْمَةِ وَقُل رَّبِّ ارْحَمْهُمَا كَمَا رَبَّيَانِي صَغِيرًا
And make yourself submissively gentle to them with compassion, and say: O my Lord! have compassion on them, as they brought me up (when I was) little.
May god Give us Taufeeq to serve our Parents throughout our life time, Aameen.
