With regard to the age of Aisha.. the youngest wife of Prophet Muhammad ... I've posted before on this some time ago on this board. There are a couple points that need to be considered. One is that there was no universal calendar at use in the time of the Prophet... So the age of these people is problematic... No one really knows the answer as to how old they were.. You can estimate with in a few years... Actually Aisha had already been engaged to marry a Meccan pagan but he broke it off when he found out she was a Muslim.
The Hadith that's oft quoted about the age of Aisha when she married was collected well over a hundred years after the events reported..
Under Caliph Omar which was quite awhile after the passing of the Prophet a Muslim calendar was adopted.
I've also wondered about the age of the first wife of Prophet Muhammad... She was supposed to be forty years old when she married Muhammad. It's reported they had five children together... Even today with the best medical care available a woman over forty having children is not that common and would be risky. The Prophet was married to Khadijih we are told for around twenty years. Monogamy was unusual for that time in Mecca.
Most of the marriages that were contracted after the passing of Khadijih were either for state reasons or with widows of some of the companions of the Prophet who lost their lives.. A Christian ruler of Egypt sent two women as "gifts" to the Prophet... The Prophet married one of them and that was Mary the Copt...She being a Coptic Christian.
So these marriages were not what some critics have alleged... usually by Christian groups be careful of your sources.
I'm attaching a note here regarding the calendar issue ... that there was no calendar in use among Muslims until the time of the Caliphate of Omar:In AD 638 (17 AH),
Abu Musa Ashaari, one of the officials of the
CaliphUmar in
Basrah, complained about the absence of any years on the correspondence he received from Umar, making it difficult for him to determine which instructions were most recent. This report convinced Umar of the need to introduce an era for Muslims. After debating the issue with his counsellors, he decided that the first year should include the date of Muhammad's arrival at Medina (known as Yathrib, before Muhammad's arrival).
Uthman ibn Affan then suggested that the months begin with Muharram, in line with the established custom of the Arabs at that time.
[21] The years of the Islamic calendar thus began with the month of Muharram in the year of Muhammad's arrival at the city of Medina, even though the actual emigration took place in Safar and Rabi' I.
[3] Because of the Hijra, the calendar was named the Hijra calendar.
