Shortening the Prayer When Traveling to a Place Where One Has a Wife or a House

Question:
If a man travels to a place where he has a wife or a house, does he shorten the prayer? What is the evidence for that?

Answer:
He does not shorten it. If he has a family in that place, if he has two wives, one in one place and one in another, he does not shorten it; he prays the full prayer. However, if that is his home and he has moved away from it, then if he is in Buraydah and moves to Riyadh, if he comes to Buraydah and is not a resident there, he shortens the prayer; there is no harm in that. It is like the Prophet (peace and blessings be upon him) was in Makkah and then moved from it to al-Madinah, and when he came to Makkah, he shortened the prayer. But if he has families in both places, his family in Makkah and his family in al-Madinah, or his family in Riyadh and his family elsewhere, he does not shorten the prayer with them because he is settled there.
