Mukhtasar Bukhari (Abridged) 40 — Most beloved deeds to Allah are

Umm al-Mu’minin Aisha Siddiqa (may Allah be pleased with her) says that (once) the Noble Prophet (peace and blessings of Allah be upon him) came to her and (saw that) there was a woman (sitting) with her. The Prophet (peace be upon him) asked: “Who is this?” Aisha (may Allah be pleased with her) replied that this is such-and-such woman (and) began to mention the abundance of her prayers. So the Prophet (peace be upon him) said: “Stop (look), take upon yourselves only as much (acts) as you are able to do (consistently), for Allah does not tire (of giving reward) until you tire (of worship), and the most beloved deed to Allah is that which is done regularly by its doer.”
