Hadith text
Narrated Abu Bakra:A man praised another man in front of the Prophet. The Prophet (ﷺ) said thrice, "Wailaka (Woe on you) ! You have cut the neck of your brother!" The Prophet (ﷺ) added, "If it is indispensable for anyone of you to praise a person, then he should say, "I think that such-and-such person (is so-and-so), and Allah is the one who will take his accounts (as he knows his reality) and none can sanctify anybody before Allah (and that only if he knows well about that person)
Abu Bakra bataate hain: Ek shaks ne Nabi (SAW) ke saamne doosre ki taarif ki. Nabi (SAW) ne teen baar kaha, 'Wailaka (afsos hai tumpar)! Tumne apne bhai ki gardan kaat di!' Nabi (SAW) ne aage kaha, 'Agar tum mein se kisi ke liye kisi ki taarif karna zaroori ho, to use kehna chaahiye, "Mujhe lagta hai falaan (aisa hai)," aur Allah hi hai jo uska hisaab lega (kyunke wo uski asliyat jaanta hai), aur koi kisi ko Allah ke saamne paakeeza nahi thehra sakta (siwaaye is ke ke use us shaks ke baare mein achhi tarah pata ho).'
