Riyad as-Salihin, Book 1, Hadith 77 (In-Book)

Abu Hurairah (May Allah be pleased with him) reported: The Prophet said, "A group of people (both men and women) whose hearts will be like the hearts of birds, will enter Jannah".[Muslim].It has been interpreted that such people are those who put their trust in Allah; another interpretation is that these people are tender- hearted.
