The Messenger of Allah ﷺ said, "In Paradise there is a gathering of the wide-eyed houris who raise their voices in song unlike anything the creation has ever heard. They sing, 'We are the eternal ones, never to perish. We are the delicate ones, never to suffer hardship. We are the contented ones, never to grow displeased. Blessed is he who belongs to us and to whom we belong.'"
حدثنا هناد وأحمد بن منيع قالا حدثنا أبو معاوية قال حدثنا عبد الرحمن بن إسحق عن النعمان بن سعد
قال رسول الله ﷺ إن في الجنة لمجتمعا للحور العين يرفعن بأصوات لم يسمع الخلائق مثلها قال يقلن نحن الخالدات فلا نبيد ونحن الناعمات فلا نبؤس ونحن الراضيات فلا نسخط طوبى لمن كان لنا وكنا له
