The Nahi (forbiddance) related to Tasarrufaat (transactions) and ‘Uqood (contracts) like trade, hiring and marriage amongst others, either represents a Nahi that returns to the ‘Ain (essence) of the contract or a Nahi returning back to a matter linked, connected or adjoined to it.

1 – If the Nahi is directed towards the ‘Ain (essence) of the contract or the Tasarruf (conduct/transaction), then there is no doubt that it impacts upon the transactions and contracts and makes them Baatil (invalid) or Faasid (corrupted). That is due to the statement of the Messenger of Allah (saw):

That means that it is not Saheeh (valid) and not Maqbool (acceptable). There is no meaning for it being described as Mardood (rejected) except Al-Butlaan (invalidity) or Al-Fasaad (corruption). Ibn ‘Umar made deduction upon the Butlaan and the Fasaad of marriage to the Mushrikaat (female polytheists) based on His Qawl (swt):

And none denied this from him and as such it represents an Ijmaa’.

This is in the case when the Nahi establishes At-Tahreem (prohibition). When, however the Nahi establishes Al-Karaahah (dislike) then it does not impact upon the Tasarrufaat and the ‘Uqood (transactions, conducts and contracts). That is because the Ta’theer (impact) comes from the Tahreem as the Tahreem of a transactional conduct or contract makes it Baatil or Faasid.

There is a difference between the Butlaan and the Fasaad which we explained in the first chapter discussing the types or categories of the Hukm Al-Wad’iy and consequently it is advisable to refer back to it.

2 – In the case where the Nahi returns back to a matter that is outside of the ‘Aqd (contract) or the Tasarruf (transaction, conduct), then the Nahi in this situation does not impact upon the ‘Aqd (contract) and even if it was Haraam. This is like trading at the time of the Adhaan of Salaat ul-Jumu’ah as the trade is Saheeh (valid), even if the act was Haraam, and its results are built upon it (i.e. of legal ownership and benefiting from it). Or it is like the Salaah performed in the usurped land (Al-Ard Al-Maghsoobah) as it is valid even though it is Haraam. It counts (is recompensed) and there is no requirement to repeat its performance although the sin results from it and is a consequence of it.
