Strive for righteousness ; Do good deeds .

This hadith tells us about the dream of Ibn 'Umar, where he saw himself holding onto a piece of silk and being able to fly with it to any place in paradise. When Hafsah told this dream to the Prophet, he said that his brother was a righteous man. This suggests that dreams can be interpreted as signs from Allah, and also shows us the importance of righteousness in Islam. It teaches us that if we strive for righteousness, Allah will reward us with good things both in this life and the hereafter. We should always strive for righteousness so we can be rewarded by Allah's mercy and grace.
