Edited sentence: According to a narrative reported by Ahmad ibn Hanbal, after the death of Khadijah when Khawla bint Hakim came to the Muhammad advising him to marry again, he asked her regarding the choices she had in her mind and Kawla said," You can marry a virgin (Bikr) or a woman who has already been married (thayyib).According to almost all the historians, Asma the elder sister of Aisha, was ten years older than Aisha.Aisha should have been eighteen or nineteen years old at that time, Thus, Aisha, if she got married in one AH or two AH her age was between eighteen to twenty years old at the time of her marriage.All those who know the Arabic language, are aware that the word "Bikr" in the Arabic language is not used for an immature six to nine year old girl.Asma is reported to die in the 73 AH, when she was 100 years old...Ibn Hisham’s recension of Ibn Ishaq’s Sirat Rashul Allah, the earliest surviving biography of Muhammad, records Aisha as having converted to Islam before Umar ibn al-Khattab, during the first few years of Islam around 610 CE.In order to accept Islam she must have been walking and talking, hence at least five years of age, which would make her at least seventeen or eighteen in 622 CE.Now if Aisha was only six or seven years old at the time of her marriage, she could not have been born at the time Abu Bakr decided on migrating to Ethiopia.Now obviously if Asma was hundred years old in seventy three Hijrah she should have been twenty seven or twenty eight years old at the time of one Hijrah.On the basis of this report it seems only reasonable to assume that Aisha had not only been born 8 years before Hijrah, but was also a young lady quite prepared for marriage.The correct word for a young playful girl, as stated earlier is "Jariyah", "Bikr" on the other hand, is used for an unmarried lady and obviously a six to nine year old is not a "lady".This was 8 years before Hijrah.When Muhammad asked who the virgin was, Khawla propsed Aisha's name
