A: It is not permissible to swear by the Ka'bah or by any other created thing, due to the saying of the Prophet (peace and blessings be upon him): It is agreed upon that it is authentic. And his saying (peace and blessings be upon him): It was narrated by Imam Ahmad from the hadith of 'Umar ibn al-Khattab (may Allah be pleased with him) with a sound chain. And his saying (peace and blessings be upon him): It was narrated by Abu Dawud and al-Tirmidhi with a sound chain from the hadith of 'Abdullah ibn 'Umar ibn al-Khattab (may Allah be pleased with them both). The hadiths on this matter are numerous, and through them it is known that swearing by the Ka'bah, by trusts, by the prophets, and by others from all of creation is forbidden.
The lawful oath is the oath by Allah alone, and its description is that one says: "By Allah," or "By Allah," or "By Allah, I will certainly do such and such," or "I will not do such and such," and so on. If one swears by any of the names of Allah and His attributes other than the Most High Name, such as al-Rahman (The Most Merciful), al-Rahim (The Bestower of Mercy), Malik al-Mulk (Lord of Sovereignty), Life of Allah, Knowledge of Allah, and the like, it is also permissible.
And the Prophet (peace and blessings be upon him) used to swear often by saying: And success is from Allah.
