The ruling on saying, "So-and-so is not the son of so-and-so"
Machine translationRead the Arabic original
The questioner:
And the case of the Shaykh (may Allah have mercy on him), where one says, "So-and-so is not the son of so-and-so," is that the matter of the qasr (shortening) is established against him?
The Shaykh:
This falls under the category of indirect accusation. This is indirect accusation. There is no direct evidence, but it is difficult. If the person about whom it is said demands proof of it, it becomes difficult. Yes.
