Narrated `Aisha: The Prophet was asked, "What deeds are loved most by Allah?" He said, "The most regular constant deeds even though they may be few." He added, 'Don't take upon yourselves, except the deeds which are within your ability."

حَدَّثَنِي مُحَمَّدُ بْنُ عَرْعَرَةَ، حَدَّثَنَا شُعْبَةُ، عَنْ سَعْدِ بْنِ إِبْرَاهِيمَ، عَنْ أَبِي سَلَمَةَ، عَنْ عَائِشَةَ ـ رضى الله عنها ـ أَنَّهَا قَالَتْ سُئِلَ النَّبِيُّ صلى الله عليه وسلم أَىُّ الأَعْمَالِ أَحَبُّ إِلَى اللَّهِ قَالَ ‏"‏ أَدْوَمُهَا وَإِنْ قَلَّ ‏"‏‏.‏ وَقَالَ ‏"‏ اكْلَفُوا مِنَ الأَعْمَالِ مَا تُطِيقُونَ ‏"‏‏.‏
