It was narrated from Hammam bin Al-Harith that 'Aishah said: "I remember when I could do no more than rub it form the garment of the Messenger of Allah ﷺ".
This hadith also reminds us that even though we may not have much power or influence in this world, it is still important for us to strive for excellence in whatever task we undertake. Even if it is as simple as rubbing something off a garment, it is important for us to put forth our best effort so that Allah will be pleased with us. We should never underestimate ourselves or think that what we do does not matter because every action counts in the eyes of Allah!
