Is the unknown voice heard during ablution a divine message?

All praise is due to Allah, who has guided and enabled you to adhere to His law. As for the voice you heard, it could have been from an angel, a human, or a jinn, and it is impossible to determine definitively which one it was. We ask Allah that it be for good, and that its purpose was to prompt you to complete your ablution and perform the prayer. Indeed, it is desirable to hasten in such matters. You should not dwell on this issue too much. Rather, ask Allah that it be good and be optimistic, for Allah loves good omens and dislikes pessimism.
