Peace and Greetings
Please correct my 1.5 cents thought process.
 You ask an elderly westerner about Prophet Moses, great chance he or she will recall 10 Commandments.
 You ask any person about Egypt, great chance that person will think about the pyramids at Giza.
 You ask especially Muslims, also people of other faith about the Exalted Messenger and Hazrat Khadija [RA], it is 25 / 40
You be the judge, to me it is 25/25
Marriage with Prophet Muhammad (s)
As Ibn Kathir quoted from Ibn Ishaq: When Khadija (a) became familiar with honesty, trustworthiness and ethical characteristics of Muhammad (s), she entrusted him her wealth. Then after Muhammad (s) came from a commercial travel from Syria, Maysara (Khadija's (a) slave) reported the characteristics of Muhammad (s) to Khadija (a). Afterwards she proposed marriage to Prophet Muhammad (s). Also Ibn Sayyid al-Nas said: when Khadija (a) was informed about the ethical characteristics and honesty of Muhammad (s), she proposed marriage to him. Ibn al-Athir also mentioned the same thing in Usad al-ghaba . According to all sources, Khadija (a) was the first wife of Prophet Muhammad (s). Ibn Abd al-Barr considered Khadija (a) as the first wife of Prophet (s) and he said Prophet (s) did not have any other wife during their marital life. He also said, Prophet (s) was 25 when he married Khadija (a), 26 years after 'Am al-Fil. As he quoted from al-Zahiri, the Prophet (s) was 21 years old when he married Khadija (a). In addition, Ibn al-Mas'udi considered Khadija (a) as the first wife of Prophet Muhammad (s). Ibn al-Athir emphasized the fact that Khadija (a) was the first wife of Prophet Muhammad (s) and he said they married before Bi'tha. He also mentioned different ages for Prophet Muhammad (s) at the time of his marriage: 21, 22, 25, 28, 30 and 37.
Age in Marriage to Prophet Muhammad (s)
Historians mentioned different ages for Khadija (a), when she married Prophet Muhammad (s), from 25 to 46. Most of sources stated that Khadija (a) was 40 years old when she married the Prophet (s). Ibn al-Mas'udi accepted the possibility of other ages (than 40 years old) for Khadija (a) in her marriage with Muhammad (s). Analyzing the exact age of Khadija (a) at the time of her marriage with Prophet Muhammad (s) is difficult. If we consider that their marriage lasted for 25 years, from 15 years before bi'tha (593 CE) to 10 years after bi'tha (618 CE), and the age of Khadija (a) when she passed away was 65 or as al-Bayhaqi said 50; therefore, we can conclude that Khadija (a) was either 40 or 25 when she married Prophet Muhammad (s). If we consider the age of Khadija (a) 50, when she passed away, then she married Prophet (s) at the age of 25, which is accepted by some of the researchers. Since this statement is not common, its acceptance would seem difficult. However if we consider that al-Qasim, Khadija (a) and Prophet's son, had passed away after Bi'tha, it means Khadija (a) was 55 when al-Qasim was born, which is unacceptable and improbable. In addition, if we consider the situation and status of Khadija (a) among Quraysh, it seems improbable that she would not marry until 40 years old; therefore, she should not be more than 25 or 28 when she married Prophet Muhammad (s).
According to sources, Prophet Muhammad (s) and Khadija (a) had seven or eight children, or as some other sources said, six children. As Ibn Kathir quoted from Ibn Ishaq and Ibn Hisham, they had seven children; all the children of Prophet (s) are from Khadija (a) except for Ibrahim b. Muhammad. He has quoted the names of six children from Yunus b. Bukayr. As Ibn al-Athir have quoted from al-Zubayr b. Bakkar, al-Tayyib and al-Tahir, Prophet's children, were named after Prophet Muhammad's Prophethood. Also other sources mentioned all the Prophet's children were from Khadija (a) except for Ibrahim. Ibn al-Athir al-Jazari has quoted from Al-Zubayr b. Bakkar the names of eight children for Prophet Muhammad (s) and Khadija al-Kubra (a). It seems the differences on the names of Prophet Muhammad (s) and Khadija's children are caused by their names and titles. Therefore, they had six children including two sons, al-Qasim and 'Abd Allah (al-Tayyib and al-Tahir as 'Abd Allah's titles) and four daughters, (Zaynab, Ruqayya, Umm Kulthum and Lady Fatima (a).
B’itha: Start of Revelation
• Do not believe in anything simply because you have heard it. Do not believe in anything simply because it is spoken and rumored by many. Do not believe in anything simply because it is found written in your religious books. Do not believe in anything merely on the authority of your teachers and elders. Do not believe in traditions because they have been handed down for many generations. But after observation and analysis, when you find that anything agrees with reason and is conducive to the good and benefit of one and all, then accept it and live up to it.
• Believe nothing, no matter where you read it, or who said it, no matter if I have said it, unless it agrees with your own reason and your own common sense.
