Once the Prophet remained behind us in a journey. He joined us while we were performing ablution for the prayer which was over-due. We were just passing wet hands over our feet (and not washing them properly) so the Prophet addressed us in a loud voice and said twice or thrice: “Save your heels from the fire.”
[Volume 1, Book 3, Number 57: Sahih Bukhai
How wonderful this Hadith is, which makes us focus on the quality of work instead of doing it haphazardly. May Allah helps us all in looking for the quality in our prayers and everyday life.
