صحيح البخاري
Sahih Bukhari
كتاب الشهادات
The Book of Witnesses
باب يحلف المدعى عليه حيثما وجبت عليه اليمين، ولا يصرف من موضع إلى غيره:
(23) Chapter. The defendant has to take an oath wherever it becomes legally compulsory, and it is not imperative to take him from his place to another place (i.e., a sacred place like a mosque) for this purpose.
