بسم الله الرحمن الرحيم
(Fatwa: 2586/2151=B/1429)
A Muslim should pray in mosque and a Hindu should go to his temple for puja. The beliefs of Muslims differ from those of the Hindus. A Muslim believes in One Allah and worships Him alone, while the Hindus worship many gods. Due to this difference of belief, if a Muslim goes to a temple or vice versa it may disrupt peace. Yes, by living mutually with tolerance and morality peace will prevail and unity and integrity will persist.
Allah knows Best!
