Four marriages of men are permissible in islam.Holy Prophet attempted 11 marriages, than why it is not allowed for men to get 11 marriages?
Men are not allowed to be married to more than four women simultaneously, because the Quran has put a limit of four:
فانكحوا ما طاب لكم من النساء مثنى وثلاث ورباع فإن خفتم ألا تعدلوا فواحدة أو ما ملكت أيمانكم ذلك أدنى ألا تعولوا
Then marry those that please you of [other] women, two or three or four. But if you fear that you will not be just, then [marry only] one or those your right hand possesses. That is more suitable that you may not incline [to injustice].
The Prophet Muhammad ﷺ was married to nine women simultaneously, and this was a specifically allowed to him see Quran 33:50-52:
There are quite a few examples of differences of law applicable to the Prophet compared to other Muslims. For example:
- The Prophet and his family can not receive Zakat, whereas any other Muslim may receive it.
- The Prophet's property is not inherited by his heirs, unlike the property of other Muslims.
- Some of the acts of worship that are voluntary for other Muslims are obligatory for the Prophet.
- The Prophet's Wives can not be married by others after his death, unlike the wives of other Muslims.
There is a list of these in Tafsir al-Qurtubi (arabic) under السادسة عشرة
