Answer
(Fatwa: 190/191=L)
If you did not leave your birthplace but own some property there and you stay in
But, if you have left your birthplace at all and do not have any property there then you will shorten your salah (qasr) in case you intend to stay less than 15 days, or if you intend to stay more than 15 days but you will be visiting other places meantime then also you will do qasr. Yes, if you intend a stay of 15 days or more at one place then you will perform full salah and in this case if you travel to a distance less than 48 miles you will pray full salah: و یبطل وطن الاقامۃ بمثلہ وبالوطن الأصلی وبانشاء السفر [الدر المختار مع الشامی: 2/614]
