question #2 Sahih Muslim 763h, Book 6, Hadith 223 : What is the significance of the phrase ‘Make me light’ in the context of this narration?

I met Kuraib and he reported Ibn `Abbas as saying: I was with my mother’s sister Maimuna and the Messenger of Allah (ﷺ) came there, and then he narrated the rest of the hadith as was narrated by Ghundar and said these words: “Make me light,” beyond any doubt.
