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.
الرابع: عن أبي هريرة رضي الله عنه عن النبي صلى الله عليه وسلم قال: "يدخل الجنة أقوام أفئدتهم مثل أفئدة الطير" ((رواه مسلم)).
