Abu Hurairah (May Allah be pleased with him) reported:
The Prophet (ﷺ) 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.
