The Prophet (ﷺ) said: "If people were given whatever they claimed (in disputes), some people would claim the lives and wealth of others; but the oath (of denial) must be taken by the defendant." [Agreed upon]. al-Baihaqi has reported with a Sahih (authentic) chain of narrators: "But the proof (Bayyinah) lies on the one who is making the claim, and the other (Yamin) must be taken by the one who rejects the claim."
