You said in this question that if the boy has intention to stay with parents after being qualified then he will be Muqeem at home and will perform full prayer and if he has not intention to stay with parents after qualification then he will be Musafir at home and will perform Kasar payer. I want to ask that in light of above both situations that suppose he is Muqeem at home then what will he be at college and if he is Musafir at home then what will he be at college.
If the boy intends to stay at the college for 15 days or more, he will be a
Muqeem there. If he does not intend to stay there for a minimum of 15 days,
he will be a Musaafir at college.
