Stipulating to a husband some conditions violating the Islamic teachings
It is not permissible for you to abide by the conditions of the family of your fiancée regarding cutting your beard short and wearing a longer dress if they mean (Part No. 18; Page No. 409) that which goes down past the ankles (in violation of the Sunnah). The same will apply if they prevent you from attending the circles of Dhikr. This is because such conditions oppose the teachings of the Book of Allah. The Prophet (peace be upon him) said,
Any condition that is not in the Book of Allah is null even if they were hundred conditions
Also, Allah's Messenger (peace be upon him) said,
Muslims are on (adhere to) their conditions, except those which turn what is unlawful into what is lawful or what is lawful into what is unlawful.
The Prophet (peace be upon him) said,
There should be no obedience to the created in disobedience to the Creator.
You should be sure that Allah (Exalted be He) will give you a wife that is better than her, as Allah (Exalted be He) says,
And whosoever fears Allâh and keeps his duty to Him, He will make a way for him to get out (from every difficulty).
And He will provide him from (sources) he never could imagine. And whosoever puts his trust in Allâh, then He will suffice him. Verily, Allâh will accomplish his purpose. Indeed Allâh has set a measure for all things.
May Allah grant us success. May peace and blessings be upon our Prophet Muhammad, his family, and Companions.
