He said: "If a man marries her and (accepted) her stipulations that he shall not remove her from her home or city (country), then her stipulation is to be honoured/ fulfilled (from that moment on) due to what has been reported from Rasul ul Allaah (saws). He said: "The most deserving of conditions to be honoured/fulfilled are those which the genitalia are deemed Halal by them (Marriage is built upon their acceptance)." 

As well if he marries her and (accepts) her stipulation that he will not marry another woman while with her then she is granted the power to abandon him if he marries another." 

The summary of (this issue) is that stipulations relating to Nikaah (pre-nuptiual agreements) are of three main categories 
(Translators note: Only the first issue is translated):

First: (A condition) that which must be fulfill. It is a condition wherein its benefit and worth are returned. Examples are stipulations wherein he (vows) not to remove her from her residence or land, or that he will not travel with her (to foreign lands), or that he will not take another wife while with her. All of these are conditions that he would be bound to fulfilling (if he agreed to them before cohabitation). If he does not honour the stipulations she is granted the ability (and right) to annul the marriage (at her will). This is reported as being the opinion of:

‘Umar bin al-Khattab, Sa‘d bin Abi Waqas, Mu‘awiyah, ‘Amr bin al- ‘Aas (radia Allahu ‘Anhom). It was also stated by:

Shurayh, ‘Umar bin ‘Abdul-Aziz, Jabir bin Zayd, Tawus, Al-Awza‘i and Ishaq."

Those who deemed these conditions unacceptable were:

(none of them Sahabah): az-Zuhari, Qatadah, Hisham bin ‘Urwa, Malik ^[1], al-Laith, ath-Thawri, ash-Shafi‘i (in part), ibn al-Mundhir, and the people of logical deduction and inference.

Abu Hanifah and ash-Shafi‘ee stated: "(If he breaks one of the aforementioned conditions she is not entitled to leaving him.) The original dowry (Mahr) is deemed invalid and she deserves another equal Mahr to what she has already been given (by her husband).

They use as their proof the statement of Rasul ul Allah (saws): "Any condition, which is not in Allaah’s Book, is worthless (invalid). Even if there are a hundred conditions. Allaah’s decision is more valid and Allaah’s condition is more binding." (Agreed upon)

(They say) such a condition is (not sanctioned) in Allaah’s Book since the Law does not espouse it.

He (saws) also said, "A Muslims are bound to their conditions /stipulations. (But) a condition that makes Halaal a Haraam or a Haraam Halaal is (not from binding conditions)." (Bukhari, Tirmidhi and others)

This (type of condition) is turning a Halaal into a Haraam. Taking more than wife, traveling (are Halaal). As well these conditions do not benefit or improve the ‘Aqd (marital pre-nuptial contract) and are not integral to it. In fact it would be similar to stipulating that she is not to present her self (ever) to him (in copulation)."

End words of Shafi‘ee and Abu Hanifah

For us (our understanding) we have the following (evidence): "The most deserving of conditions to be honoured/fulfilled are those which the genitalia are deemed Halaal by them (Marriage is built upon their acceptance)."
Agreed Upon.

As well his statement (saws): "Muslims are bound to their conditions/stipulations." (Previously referenced)

As well we have named many Sahaba who validated these stipulations, and none from their generation / peers refuted them. Therefore we establish this as being Ijma‘ (consensual agreement by them all).

It is narrated by al-Athram with his chain of narration that a man married a woman and (agreed to the stipulation) that she may reside in her (own) home. Thereafter he sought to transfer her elsewhere. They turned to ‘Umar (Ra) in disputation.

He (Ra) said "Her condition is to be fulfilled."

The man replied, "If that is the case then she is to grant the divorce (he means that she is to relinquish her condition or divorce him)."

‘Umar (ra) replied, "The absolute rights are (established with their) stipulations (His right is over-ruled by his agreement to her stipulation)." ^[2]
