Is it permissible to designate the night of Monday or the night of Friday for specific supplication?

The questioner:
We ask you to tell us, may Allah reward you with good, about the regular practice performed on the night of every Monday and every Friday.

The Shaykh:
And what is this regular practice?

The questioner:
They described it here by saying that the regular practice consists of supplications from al-Di'bi, taken from a book, and we recite them in a loud voice.

The Shaykh:
In the name of Allah, the Most Gracious, the Most Merciful. Praise be to Allah, Lord of the worlds, and may Allah send prayers and blessings upon our Prophet Muhammad, his family, and all his Companions. As for what follows, it is obligatory for the Muslim not to perform any act unless it conforms to the Book and the Sunnah, and he must know its evidence from the Book and the Sunnah. What these brothers mentioned regarding gathering for supplication on the night of Monday with a collective voice and specific supplications, all of this has no evidence.
Yes, it is required of the Muslim to supplicate to Allah (Mighty and Majestic), and supplication is the best type of worship. Allah (Glorified and Exalted is He) said: . He (Glorified and Exalted is He) said: . And the Prophet (peace and blessings be upon him) said: "Supplication is worship," meaning it is the greatest type of worship.
However, arranging supplication at a specific time or on a specific night, or designating a specific type of supplication, requires evidence. There is no evidence for designating the night of Monday, nor for gathering in this manner with a collective voice. All of this is among the innovations and bid'ah (religious innovations).
The Muslim supplicates to Allah on the night of Monday and on nights other than Monday, but without gathering or arrangement, and without a collective voice. He does not designate a specific night unless there is evidence indicating that, such as the Night of Decree. Supplication on the Night of Decree has a distinction because Allah (Exalted and Majestic is He) singled it out with additional favor. Likewise, supplication on the Day of 'Arafah; the Prophet (peace and blessings be upon him) said: It is not permissible to designate any day for supplication, or any night for supplication, unless there is evidence. Otherwise, the Muslim supplicates to Allah on all nights, on all days, and on every occasion, especially when he has a need for supplication, for then it becomes more emphasized for him. What the brothers mentioned regarding this supplication in the described manner, on the described night, and in the described form, is a bid'ah (religious innovation) that must be abandoned. Yes.

The presenter:
May Allah reward you with good, and may Allah reward you. In addition to the night of Monday, what about the night of Friday, Shaykh Fawzan? Is the answer the same? May Allah reward you with good?

The Shaykh:
Nothing has been transmitted regarding designating the night of Friday with something specific for supplication in it. Yes, the night of Friday and the day of Friday are a noble day. The Prophet (peace and blessings be upon him) said: This hour is on the day of Friday, but Allah concealed it within it so that the Muslim would strive in supplication throughout this entire day. This is regarding the day of Friday. As for the night of Friday, I do not know of any evidence indicating that it is designated for supplication. Rather, what has been transmitted is to increase the sending of prayers upon the Prophet (peace and blessings be upon him).

The presenter:
Your work is done.

The Shaykh:
On the night of Friday and on its day, and the Muslim, as we mentioned, only does what has evidence for it.
