“I am only human, and some of you may be more eloquent in presenting your case than others. If I pass a judgement in his favor that detracts from his brother's rights, I am giving him a piece of fire.”
“If the people were given what they claimed, some would have claimed the lives and property of men. But the one the claim is made against is obliged to swear an oath.”
“There was a dispute between myself and a Jewish man concerning some land, and he denied me my rights so I brought him to the Prophet (ﷺ). The Messenger of Allah (ﷺ) said to me: 'Do you have proof' I said: 'No.’ He said to the Jews, 'Swear an oath.' I said: 'If he swears an oath he will take my property.' Then Allah, Glorious is He, revealed: 'Verily, those who purchase a small gain at the cost of Allah's covenant and their oaths, they shall have no portion in the Hereafter (Paradise). Neither will Allah neither speak to them nor look at them on the Day of Resurrection nor will He purifies them, and they shall have a painful torment.'”
“No man seizes the wealth of a Muslim unlawfully by means of his (false) oath, but Allah will deny Paradise to him and will doom him to Hell.” A man among the people said: “O Messenger of Allah, even if it is something small?” He said: “Even if it is a twig of an Arak tree.”
I heard Abu Salamah say: I heard Abu Hurairah say: “The Messenger of Allah (ﷺ) said: 'No man or woman swears a false oath beside this pulpit, even if it is for a fresh twig, but he will be doomed to Hell.”
