أَحَبُّ الْأَعْمَالِ إِلَى اللَّهِ أَدْوَمُهَا وَإِنْ قَلَّ
The deeds most beloved to Allah are those maintained most consistently, even if few.
Source: Bukhari and Muslim.
أَحَبُّ means “most beloved,” and أَدْوَمُهَا means “those maintained most steadily.” The pronoun ـهَا refers back to الْأَعْمَالِ, the deeds. وَإِنْ قَلَّ means “even if it is little.”
The point concerns good, religiously acceptable deeds, not merely repeating any habit. It does not justify neglecting obligatory duties in favor of easy optional acts.
For example, reserving a little time each day for careful Qur’an study can cultivate consistency more effectively than occasional unsustainable bursts.
