Can I inquire about the age of Ummul Mu'mineen Lady Khadijah Kubra (as) at the time of her marriage to the Prophet (s)? Specifically, what is Ayatollah Basem Al Sheraa's (ha) opinion on whether she was 28 or 25 years old?
We have even in Sunni books that the age of Khadijah (AS) when she got married with the Prophet (SAWA) was 25 years. (AL-BIDAYAH WAL-NIHAYAH by Ibn Katheer , Volume 2, page 295. Al-Bayhaqi (Dala'il Al-NUBOWWAH) 2/ 71).
Other Sunni books narrated that her age was 28 years (Tabaqaat ibn Sa'd 8/ 17 and Al-Mustadrak by Al-Haakim al-Nisabori 3 : 182).
Wassalam.
