Mukhtasar Bukhari

Narrated Ibn Abbas (may Allah be pleased with them) that when the Prophet (peace and blessings of Allah be upon him) returned from his Hajj, he said to Umm Sinan Ansariyyah: "What prevented you from performing Hajj?" She replied, "So-and-so" (referring to her husband) "had two camels for carrying water; he went for Hajj on one, and the other is used to irrigate our land." The Prophet (peace and blessings of Allah be upon him) said: "Well, then perform Umrah, for indeed performing Umrah in Ramadan is equivalent to performing Hajj with me."

`Sayyiduna Abu Sa'id Khudri (may Allah be pleased with him)`, who participated in twelve battles with the Noble Prophet (peace and blessings of Allah be upon him), used to say that I heard four things from the Messenger of Allah (peace and blessings of Allah be upon him), which I found good and pleasing (these are the things): "No woman should travel for two days without her husband or a mahram, and one should not fast on two days, i.e., Eid al-Fitr and Eid al-Adha, and after two prayers, i.e., after the Asr prayer until sunset and after the Fajr prayer until sunrise, no prayer should be performed, and one should not undertake a journey except towards three mosques: Masjid al-Haram (i.e., the Ka'bah), my mosque (i.e., Masjid Nabawi), and Masjid al-Aqsa (i.e., Bayt al-Maqdis)."
