Shortening Salah in the place where a person has a wife

A: It is not permissible to shorten and combine Salah in every place you have a wife. However, the four-Rak`ah Salah (Prayer consisting of four units) should not be shortened nor should Salah be combined if the husband stays in the place where the wife resides or for a period of time that ends the case of travel. However, if they are staying in a place where they have wives for a period of time that does not end the case of travel, they may shorten Salah, because it is not their homeland. The Prophet (peace be upon him) married Khadijah in Makkah and migrated to Al-Madinah. When he returned to Makkah for the Farewell Hajj, he shortened his Salah.May Allah grant us success. May peace and blessings be upon our Prophet Muhammad, his family, and Companions.
