Sahih Muslim Book 31, Hadith Number 5896.
Chapter : The excellent qualities of ‘Umar (Allah be pleased with him).
Jabir reported Allah’s Messenger (may peace be upon him) as saying: I entered Paradise and saw in it a house or a palace. I said: For whom is it reserved? They (the Angels) said: It is for ‘Umar b. Khattab. (The Holy Prophet said to ‘Umar b. Khattab): I intended to get into it but I thought of your feelings. Thereupon ‘Umar wept and said: Apostle of Allah, could I feel any jealousy in your case?
