Hadith 961:133
Muhammad ibn Bishr narrated to us, Mis'ar narrated to us, from 'Abd al-Malik ibn Maysarah, from Mus'ab ibn Sa'd, from Mu'adh, who said: 'Umar was indeed among the people of Paradise. The Messenger of Allah (peace and blessings of Allah be upon him) — whatever he saw in his wakefulness or his sleep, it is the truth. And he said: "While I was in Paradise, I saw a house in it, so I said: 'Whose is this?' It was said: 'For 'Umar ibn al-Khattab.'"
حدثنا محمد بن بشر، حدثنا مسعر، عن عبد الملك بن ميسرة، عن مصعب بن سعد، عن معاذ قال: إن كان عمر لمن أهل الجنة إن رسول الله صلى الله عليه وسلم كان ما رأى في يقظته أو نومه فهو حق وإنه قال: " بينما أنا في الجنة إذ رأيت فيها دارا فقلت: لمن هذه؟ فقيل: لعمر بن الخطاب "
