What is the validity of determining the Night of Decree based on the dreams of some righteous people?

Question:
The questioner says: It has spread via mobile phone messages in the last ten days of Ramadan that the Night of Decree has been determined, and that this was done through the dream of some righteous people. It is mentioned that this has happened in past years. What is the criterion for this?

Answer:
By Allah, this is knowledge that the Messenger of Allah (peace and blessings be upon him) did not know. The Messenger did not know it, nor did he specify it for the people; rather, he encouraged them to seek it in the odd nights. He (peace and blessings be upon him) used to seek it, but he did not specify it. This means that someone came after the Messenger and claimed to know it. What is this lying and fabrication? Beware of these mobile phones, for they have become a means of promoting bid'ah (religious innovations), superstitions, and false messages, which are mostly lies. Yes.
