Samurah (May Allah be pleased with him) reported:
The Messenger of Allah ﷺ said, "Last night two men (angels) came to me (in a dream) and made me ascend a tree and then admitted me into a nice and excellent house, the like of which I have never seen before. One of them said: 'This house is the house of martyrs'."

[Al-Bukhari].

وعن سمرة رضي الله عنه قال: قال رسول الله ﷺ : “رأيت الليلة رجلين أتياني فصعدا بي الشجرة وأدخلاني دارًا هي أحسن وأفضل، لم أر قط أحسن منها، قال أما هذه الدار فدار الشهداء" (5)
