Were Uthman and Ruqayyah the first to emigrate for the sake of Allah after Ibrahim and Lut, as stated in "Ar-Raheeq Al-Makhtum" quoting from "Zad Al-Ma'ad"?

The report stating that Uthman (may Allah be pleased with him) was the first to emigrate with his family after Lot (peace be upon him) has appeared in some narrations, but their chains of transmission are weak, with some being extremely weak, fabricated, or denounced (munkar).
