Expiation for a vow of sin and for what the vow-maker does not possess

Question:
Honorable Shaykh, may Allah grant you success, is there an expiation for a vow of sin, or for what a human being does not possess, or for a vow regarding matters that are obligatory in the first place? Is there an expiation for these?

Answer:
The pleasure of what the House of Allah does not do, he does not do it by bleeding. The saying of the Messenger (peace and blessings be upon him) he does it, but they differed on whether the expiation is binding, whether a vow expiation is required in it or not. This is based on his statement. The correct view is that no expiation is required in it, because the Messenger (peace and blessings be upon him) said here: "And whoever vows to disobey Allah, let him not disobey," and he did not say: "Let him expiate," as is the case with oaths. Yes.
