Aishah (May Allah be pleased with her) reported:
The Prophet (ﷺ) came in when a woman was sitting beside me. He asked me, "Who is she?" I said: "She is the one whose performance of Salat (prayer) has become the talk of the town." Addressing her, he (ﷺ) said, "(What is this!) You are required to take upon yourselves only what you can carry out easily. By Allah, Allah does not withhold His Mercy and forgiveness of you until you neglect and give up (good works). Allah likes the deeds best which a worshipper can carry out constantly".[Al-Bukhari and Muslim].
