Strive for purity & innocence in your heart; Be loving & kind; Be humble; Obey Allah's commands; Do good deeds; Have faith in God's promise for reward after death.

This hadith is about the importance of having a pure heart in order to be able to enter paradise. It is narrated by Abu Huraira, who reported that Allah's Messenger said that people with hearts like those of birds would enter paradise. This means that these people have hearts which are free from any kind of evil or bad intentions, and they are full of love and kindness towards others. They are also very humble and obedient to Allah's commands. These qualities make them worthy enough to be rewarded with the highest level in paradise, which is a place where all good deeds will be rewarded with eternal bliss and joy. The lesson here for us is that we should strive to keep our hearts clean from any kind of sin or wrong-doing so that we can attain this highest level in paradise as well.
