Does frequent adjuration of others, such as "for God's sake" (literally, "by God upon you") and "I adjure you by God," fall under the prohibition mentioned in the verse: "And do not make [the name of] Allah an excuse in your oaths"? Is the one adjured sinful if he does not fulfill the request or forgets, and is expiation obligatory upon the one who adjures?

Frequent swearing unnecessarily is blameworthy in Islamic law, whether the swearer swears for himself or against someone else, based on the Almighty's saying: ﴿And do not make Allah an object for your oaths﴾ [Al-Baqarah: 224], and His saying: ﴿And guard your oaths﴾ [Al-Ma'idah: 89].

Indeed, the statement of one who says: "By Allah, you shall do such and such" is a binding oath, and expiation is due upon the swearer if what he swore upon is not done, not upon the one against whom he swore.

As for saying: "By Allah, I ask you" or "I implore you by Allah," if the intention is to ask by the Face of Allah, then this is prohibited in Islamic law except for Paradise, based on the saying of the Prophet, peace and blessings be upon him: «Accursed is he who asks by the Face of Allah, and accursed is he who is asked by the Face of Allah and then withholds from his asker what he has asked, unless he asks for something worthless», and his saying, peace and blessings be upon him: «Nothing is asked by the Face of Allah except Paradise.» If the intention is to request an oath, then nothing is incumbent unless the other party actually swears.

Fulfilling the oath of one who swears is recommended for whoever is able to do so and if it does not result in harm or sin, based on what is narrated in the Two Sahihs from Al-Bara' bin 'Azib, may Allah be pleased with him, who said: "The Messenger of Allah, peace and blessings be upon him, commanded us seven things and forbade us seven things," and among them he mentioned fulfilling an oath.

A Muslim must glorify his Lord, so he should not swear by Him excessively or ask by Him in trivial matters.
