Mohammed as well married Aysha a 6(9) years old girl and destroyed other religions
I don't think Aisha was anywhere near that young myself, despite what some hadiths indicate, for the following reasons.
She is supposed to have accepted Islam soon after her father who
became a Muslim almost immediately after the Prophet raised His Call
in 610 A.D. That suggests to me she must have been at the age of
discretion by then, say seven or eight at least. She was already
engaged at the time to the pagan Jubair in 615 A.D. when Muslims fled
to Ethiopia in that year. She ended up accompanying them when Jubair
refused to solemnize the wedding. The formal marriage or niikah with
Muhammad does not take place until the tenth year of the Call, which
makes it 620 A.D. So if she accepted Islam when her father did in 610
A.D. at the age of about seven or eight that would make her about
seventeen at the time of their marriage. Their marraige
isn't consummated until two years after the hijra which was in 624
A.D. This would put Aisha's age at the consummation of their marriage
at more than 19 and perhaps as old as 21.
Now my math could be a bit off here as I can't see why Muhammad would
not have consummated the marriage earlier if she were already in her
late teens. There are some hadiths which claim she was five years
younger than Muhammad's eldest daughter Fatima, who was born around
605 A.D. Following that chronology she would have formally married
Muhammad at 10 and consummated the marriage at 13 which would coincide with when we would ordinarily expect a girl to reach puberty and even the hadiths which suggest a very young marriage age admit that Muhammad does not consummate the marriage before puberty.
If these hadiths which record Aisha's age at the time she married the
Prophet at seven or nine years old are inaccurate, why were they
invented in the first place? My guess is that they came out of Sunni
Islam which wished to give Aisha a place as Muhammad's young 'darling'
that would have otherwise belonged to Fatima, His eldest daughter.
However, what is *most* unfortunate about these hadiths which assign a young age to Aisha, is not the accusations which Christians unfairly make against Muhammad but acts condone in some Muslim countries today which are justified on the basis of these ahadith. Let me give you an example. Based on the fact that Aisha was supposedly able to give consent to marriage at nine, this is the age of majority for girls in Iran. It is not that girls are getting married that young, or vote or anything else, but they can be convicted as adults for crimes like prostitution which carry the death
penalty! There was one case of a thirteen year old mentally challenged
girl that had been put out for prostitution by her mother. If you can
believe it, the courts *hung* this little girl.
Mind you, the age of majority for a male is fifteen.
Now, as for Muhammad "destroying" other religions, that simply isn't the case as the the covenant Muhammad made with a Christian monastery indicates:
"This is a message from Muhammad ibn Abdullah, as a covenant to those who adopt Christianity, near and far, we are with them. Verily I, the servants, the helpers, and my followers defend them, because Christians are my citizens; and by Allah! I hold out against anything that displeases them. No compulsion is to be on them. Neither are their judges to be removed from their jobs nor their monks from their monasteries. No one is to destroy a house of their religion, to damage it, or to carry anything from it to the Muslims' houses. Should anyone take any of these, he would spoil God's covenant and disobey His Prophet. Verily, they are my allies and have my secure charter against all that they hate. No one is to force them to travel or to oblige them to fight. The Muslims are to fight for them. If a female Christian is married to a Muslim, it is not to take place without her approval. She is not to be prevented from visiting her church to pray. Their churches are to be respected. They are neither to be prevented from repairing them nor the sacredness of their covenants. No one of the nation (Muslims) is to disobey the covenant till the Last Day (end of the world)."
