Swear by saying "By The Lord Of The Ka'Bah" & "Whatever Allah Wills Then What You Will"

This hadith is about how one should swear an oath in Islam. A Jew came to the Prophet and accused him of setting up rivals to Allah and associating others with Him. In response, the Prophet commanded them that if they wanted to swear an oath, they should say “By the Lord of the Ka’bah” and “Whatever Allah wills, then what you will”. This hadith teaches us that when we are swearing an oath or making a promise we must remember that it is ultimately up to God's will whether it comes true or not. We must also remember that our words have power so we should be careful when speaking as our words can have consequences for ourselves as well as those around us.
