What is the ruling on an endowment whose proceeds are designated for purchasing animals for slaughter and holding feasts in the month of Rajab to be distributed to the poor, and what should be done with the endowment's proceeds if it is said that it is impermissible?

The Waqf superintendent is requested to purchase sacrificial animals from the Waqf's revenue and distribute them to the poor, while avoiding the allocation of the slaughter specifically to the month of Rajab; this is because the Waqf is to be operated in a manner free from objectionable practices, and the slaughter and distribution can take place in any other month as specified by the endower.
