A person made a vow but was unable to fulfill it; what is required of him?

I vowed to perform i'tikaf (spiritual retreat in the mosque) in the last ten days of Ramadan in the Sacred House of Allah, if the purpose I am striving to complete is realized. On another occasion, I said: whether that matter is realized or not, I will perform i'tikaf. But I was unable to do so. What is required of me?
Answer: If you vowed to perform i'tikaf in the last ten days of Ramadan in the Sacred Mosque, on the condition that your desired outcome is achieved, and that outcome was achieved, then it is obligatory for you to perform i'tikaf. If you missed that, then you must repent to Allah (Mighty and Majestic) for your negligence. You must pay the expiation for a broken oath, and you must also perform i'tikaf, even if it is not in Ramadan. This is based on the saying of the Prophet (peace and blessings be upon him): narrated by al-Bukhari in the Sahih. So you must fulfill the vow, and you must pay the expiation for a broken oath for the time you specified that has passed. You must also seek forgiveness from Allah and repent to Him for your negligence. And Allah is the One to be asked for help. Yes.
