If a pilgrim observes the first Tahallul before they perform Tawaf-ul-Ifadah

Q 5: One of my friends told me that there is a Hadith that indicates that if a pilgrim observes the first Tahallul (removal of the ritual state for Hajj and `Umrah) but the sun sets before they perform Tawaf-ul-Ifadah (final obligatory circumambulation of the Ka`bah in Hajj), it is obligatory on them to wear the Ihram (clothing worn during the ritual state for Hajj and `Umrah) and return to the state of Ihram (ritual state for Hajj or `Umrah) as they were. We hope that you will illustrate this.

A: The Hadith that you have mentioned is narrated by Um Salamah. However, Al-Nawawy mentioned that scholars agreed that it is inapplicable because it's Isnad (chain of narrators) is weak.May Allah grant us success. May peace and blessings be upon our Prophet Muhammad, his family, and Companions.
