Vows of obedience in the month of Rajab

The questioner:
He says: Honorable Shaykh, may Allah grant you success. Many people believe that worship in Rajab is superior, and based on this, they make vows in Rajab for various types of obedience. Is it obligatory to fulfill these vows, given that they hold beliefs from the pre-Islamic age of ignorance, or is this considered a vow of sin?

The Shaykh:
This is a bid'ah (religious innovation). Vowing worship specifically in Rajab is a bid'ah, and it is not permissible to fulfill a bid'ah. Yes.

The questioner:
He says: Honorable.

The Shaykh:
It is a vow of the prohibited, because bid'ah is forbidden. And it has not been established that there is any special virtue in working in Rajab, or that deeds performed in it have a special merit. Nothing of this has been established.

The questioner:
Honorable Shaykh, she says.

The Shaykh:
The Khurramiyyun always strive for what has no basis. And they do not pay attention to what has a basis. Glory be to Allah. They do not pay attention to what has a sound basis. And they strive for and seek out what has no basis. This is part of the fitnah (trial, discord or temptation). Yes.
