Does settling in a place for four days permit shortening Salah?

A: If you settle in this place more than four days with the intention of remaining there, you should offer Salah in full and (Part No. 8; Page No. 93) at its due time. On the other hand, if you stay less than this period, you should shorten the four-Rak`ah Salah and offer each one at its due time or combine Zhuhr and `Asr Prayers in the due time of either of them and Maghrib and `Isha' in the due time of either of them. Indeed, the matter is flexible, but it is preferable to offer each Salah at its due time in this case.May Allah grant us success. May peace and blessings be upon our Prophet Muhammad, his family, and Companions.
