Hadith text
Narrated Abu Dhar:The Prophet (ﷺ) said, "If somebody claims to be the son of any other than his real father knowingly, he but disbelieves in Allah, and if somebody claims to belong to some folk to whom he does not belong, let such a person take his place in the (Hell) Fire
Abu Dharr bataate hain: Nabi ne kaha, "Agar koi jaanboojhkar apne asli baap ke siwa kisi aur ka beta hone ka daava kare, usne Allah ka inkaar kiya hai, aur agar koi apne aap ko kisi aise qabile ka batata hai jiska woh nahi hai, use apni jagah Dozakh mein leni chahiye."
