(Fatwa: 822/927/L=08/1437)
If you have arranged the due expenses and rights of your parents and they do not need physical care then you may go in jamah without their permission. But if your parents are poor and there is none to look after them while the friends of locality or mosque have not solved this issue then it is necessary for you to attend them.
فی الھندیۃ: “وإن كان لا يخاف الضيعة عليهما بأن كانا موسرين ولم تكن نفقتهما عليه … كان له أن يخرج بغير أذنهما” (الهندية 5/365، زكريا قديم)، (كتاب النوازل 2/381).
Allah knows Best!
