Uthaimeen on Oaths
Shaikh ’Uthaimeen, may Allaah have mercy on him, said, “I wish that a person wouldn’t swear by Allaah frequently. If he needs to take an oath let him couple it with [a mention of] Allaah’s Will, saying, ‘By Allaah, inshaa Allaah …’ for in doing so he attains two great benefits. The first is that Allaah will facilitate for him what he took an oath for, and the second is that if he is not able to fulfil it he doesn’t have to carry out an expiation [kaffaarah].”
