The Ruling on Fasting on Thursday

Question:
May Allah grant you the correct path, Honorable Shaykh. This caller says: One of the students of knowledge told me that fasting on Thursday is not an anomaly (shadh), so what is your opinion on this matter?

Answer:
The standing prayer on Monday and the fourth day of the month is from the Messenger (peace and blessings be upon him). It is the connection. He fasts two days of the week: Monday and Thursday. This is established, there is no doubt in it, if Allah wills. Yes. But people appear to contradict people and cast doubt on people in their righteous deeds, and they cast doubt on people regarding righteous deeds, while they do not do anything. The strange thing is that they do not do anything, but when they see someone doing something and striving in voluntary acts, they go around casting doubt on him: "This is a lie, this is weak," and so on. They just confuse people about the deed, and this is a sign of evil; it is a sign. Yes.
