English Translation of Hadith
Hazrat Wathilah bin Al-Asqa (May Allah be pleased with him) reported: Messenger of Allah [SAWW](PBUH) said, "Of the worst lies are: to claim a false father, or to pretend to have seen what one has not seen (tell a false dream), or to attribute to the Messenger of Allah [SAWW](PBUH) what he has not said.” (Like fabricating false Hadith)
[Al-Bukhari Volume 4, Book 56, Hadith Number 712].
Lesson : as mentioned above in Surah Al-AhzabAyat 05. “Call them (adopted sons) by (the names of) their fathers, that is more just with Allah” The serious nature is the case where fabricated sayings and acts are attributed to the Messenger of Allah [SAWW](PBUH). Unfortunately, some unwary `Ulama’, particularly the story-telling preachers, frequently indulge in uttering fabricated Ahadith. The warning equally holds good in case a man narrates a Hadith of a weak chain of transmission without pointing to its category. One should, therefore, refrain from recounting all Ahadith of such a category. Also this Hadith makes another point that disown one’s father and attribute fatherhood to somebody else is a major sin, because apart from causing doubts and confusion in people’s minds about one’s blood, descent and character, this will give rise to social, moral and psychological problems as well.
