What is the ruling on a vowed prayer during the prohibited times?
Machine translationRead the Arabic original
The questioner : Now, a vowed prayer during the prohibited times, such as when a person says to Allah, "I have vowed to pray two rak'ahs." This is an absolute vow. Is it permissible to pray during the prohibited times, or is it not permissible?
The Shaykh : There are two views on this, the most famous of which is that it is permissible, but the correct view is that it is not permissible.
The questioner : It is correct that it is not permissible, except if the cause of the vow occurs during the prohibited times.
The Shaykh : Yes.
The questioner : For example, if he says, "If so-and-so arrives, I have vowed to Allah to pray two rak'ahs," and so-and-so arrives during the prohibited times, for instance after the 'Asr prayer,
The Shaykh : then in this case we say it is permissible to pray, because the cause of the prayer occurred during the prohibited times, so it becomes a prayer with a cause. A prayer without a cause is not permissible during the prohibited times.
