عَنْ عَائِشَةَ رَضِيَ اللَّهُ عَنْهَا قَالَتْ قَالَ رَسُولُ اللَّهِ صَلَّى اللَّهُ عَلَيْهِ وَسَلَّمَ:
((إِنّ اللَّهَ تَعَالى يُحِبّ إِذَا عَمِلَ أَحَدُكُمْ عَمَلاً أَنْ يُتْقِنَهُ ))

It has been narrated from Aisha RA that the Prophet ASWS said: Allah loves that when you do something, you do it with excellence.
