Qaza'ah, the freed slave of Ziyad, says: I heard Sayyiduna Abu Sa'id al-Khudri (may Allah be pleased with him) narrating from the Prophet (peace and blessings be upon him) that he (peace and blessings be upon him) said: "Four things please me: (1) No woman should travel for more than three days except with a mahram. (2) The prohibition of fasting on the days of Eid al-Fitr and Eid al-Adha. (3) There is no prayer after Fajr and Asr until the sun rises and sets. (4) Travelling to three mosques: the Sacred Mosque, the Mosque of the Prophet, and al-Aqsa Mosque, or Bayt al-Maqdis."
