Whose hearts will be like the hearts of birds, will enter Jannah
Abu Hurairah (May Allah be pleased with him) reported: The Prophet (pbuh) said, “A group of people (both men and women) whose hearts will be like the hearts of birds, will enter Jannah”.
Small birds are free of feelings such as hatred and vengeance. Looking at a little bird, you will immediately recognize that it is an embodiment of sweetness, tenderness and innocence. That is why the dove has been universally declared a symbol of peace.
According to the above-quoted hadith, this is the heavenly quality that every individual who is desirous of Paradise must have. A heavenly personality is one that is completely free of all negativity. The bird has this positive quality by virtue of its instinct, whereas a heavenly personality has this quality as a conscious choice.
A heavenly personality is one who has moulded himself in such a way that his heart is completely devoid of feelings such as hatred and vengeance; who is able to control anger; who does not react negatively to situations; who can respond with love despite hatred from others; who can do good to people selflessly; who is able to live amongst people, considering all of them as his brothers and sisters; who averts all evil, seeking out the company of angels; who patiently bears all complaints; who carries out his duties and asks his rights from God—these are those superior qualities which make people deserving of entering Paradise.
