The following oaths are not considered, nor is kaffarah necessary. For example, a person says: “If I carry out a certain act, my hands must break”, “my eyes must burst”, “I must be afflicted by leprosy”, “my entire body must disintegrate”, “the anger of Allah Ta’ala must descend”, “the skies must be rendered asunder”, “I must become an absolute pauper”, “the punishment of Allah must descend”, “the curse of Allah must fall on me”, “If I carry out a certain act, I will eat pork”, “at the time of death, I will not be able to recite the kalimah“, “on the day of judgement, I will be ashamed in the presence of Allah and His Rasul sallallahu alayhi wa sallam”.
An oath that is taken in the name of anyone other than Allah Ta’ala is not considered. For example, taking an oath in the name of Rasulullah sallallahu alayhi wa sallam, in the name of the Ka’bah, one’s eyes, one’s youth, one’s limbs, one’s father, one’s children, one’s beloved ones,one’s head, one’s life, taking an oath in the name of the person who is being addressed, an oath in one’s own name. Oaths of this sort are not considered. Acting contrary to them does not make kaffarah necessary. However, it is a major sin to take an oath in the name of anyone other thanAllah Ta’ala. Many prohibitions are mentioned in this regard in the Hadith. To take an oath in the name of anyone other than Allah Ta’ala is an act of shirk. One should abstain from taking oaths in the name of anyone other than Allah Ta’ala.
A person says: “The food of your house is haraam upon me” or “I have made a certain thing haraam upon myself”. By his saying this, that thing will not become haraam upon him.However, this oath is considered. If he eats that thing, he will have to give kaffarah.
By someone else taking an oath on you, the oath is not considered. For example, a person tells you: “I swear by Allah that you have to do this work!” This oath is not considered and one can act contrary to it.
An oath is not considered if “Insha Allah” is said together with the oath, e.g. a person says: “I swear by Allah that Insha Allah I will not do that work.” This oath will not be considered.
