ما حكم الصلاة وراء إمام يطلب من شخص أن يشهد شهادة زور في المحكمة؟

If the Imam asks someone else to bear false witness for him, this is a sin that requires repentance. He should be advised and guided gently and wisely. Prayer behind him is valid, especially if this was a slip on his part and he is known for his righteousness.
