Hadith on Habits: Best good deeds done consistently, even if easy

Umm Salamah reported: By the One who took the Prophet’s soul, peace and blessings be upon him, he did not die until he prayed most of his prayers sitting down. The most beloved deeds to him were righteous deeds that a servant performs regularly, even if they are easy.
