i had heard that our hair will cover us on judgement day wen we'll have no dress. Is it true. Plz give hadith which states....

All perfect praise be to Allaah, The Lord of the Worlds. I testify that there is none worthy of worship except Allaah, and that Muhammad, sallallaahu ‘alayhi wa sallam, is His slave and Messenger.

We have not come across this in any Hadeeth or narration of the early Muslims or the statements of the scholars and it contradicts the authentic Ahaadeeth that state that the people will be resurrected naked. ‘Aa’ishah narrated that the Prophet said: "No doubt, you will be resurrected (on the Day of Judgment) barefooted, naked and uncircumcised." ‘Aa’ishah said: I said: "O Messenger of Allaah! Will the men and women look at each other?" He said: "The situation will be too difficult for them to pay attention to that." [Al-Bukhari and Muslim]
