Nu'aim b. 'Abdullah al-Mujmir reported: I saw Abu Huraira perform ablution. He washed his face and washed it well. He then washed his right hand including a portion of his arm. He then washed his left hand including a portion of his arm. He then wiped his head. He then washed his right foot including his shank, and then washed his left foot including shank, and then said: This is how I saw Allah's Messenger ﷺ perform his ablution. And (Abu Huraira) added that the Messenger of Allah ﷺ had observed: You shall have your faces hands and feet bright on the Day of Resurrection because of your perfect ablution. He who can afford among you, let him increase the brightness of his forehead and that of hands and legs.
This hadith teaches us about the importance of cleanliness in Islam which is why Muslims are encouraged to perform wudu before every prayer or any other religious activity such as reading Quran or entering a mosque etc., so they can be spiritually clean before engaging in any religious activity. Moreover, this hadith also teaches us about being mindful even while performing mundane activities such as washing our face because it could be beneficial for us on Judgment day when we will be judged for our deeds here on earth according to Islamic teachings.
