Ruling on using a bus belonging to a Qur’an memorisation school for other charitable purposes that are not connected to it
Question

                My question is: I work in a Qur’an memorisation institute that is composed of a mosque, women’s section, facilities for washing the dead prior to burial, and so on. I am a supervisor of the women’s department. The school has a number of buses, and the brothers in the mosque asked for a bus so that the mosque students can go to pray Taraweeh in several other mosques. I told them that the bus belongs to the institute and it is not right to use it for other purposes, but they told me not to be so strict, because the businessman donated it for good purposes, and what we are doing is something good. Please advise me, may Allah bless you.
Praise be to Allah.
		One of the established principles of Islamic teaching is 
		that everyone who acts on behalf of another person should act in his 
		best interests. Therefore, what the supervisor of the institute must do 
		is not use the buses belonging to that institute for anything other than 
		the institute own interests.

	As-Suyooti said: 

	When somebody is acting on behalf of another person, it is 
	stipulated that he should act in his best interests.

	Al-Qarraafi said: It should be understood that with regard to 
	anyone who takes up the position of caliph and any position below that, it 
	is not permissible for him to do anything except that which will be in the 
	best interests of that position and ward off harm, because Allah, may He be 
	exalted, says (interpretation of the meaning): “And 
	come not near to the orphans property except to improve it” 
	[al-Isra’ 17:34].

	End quote from al-Furooq (4/76)

	You did well by not allowing them to transport the mosque 
	students to Taraaweeh prayer in the bus belonging to the Qur’an memorisation 
	school, because this is not one of the interests that will benefit the 
	women’s section.

	If the bus is a waqf that was set up as such by the donor, 
	then in such cases reference must be made to the conditions he made when 
	giving the waqf. If he gave it as a waqf specifically to the women’s section 
	, then it should not be used for any other purpose that is not connected to 
	the women’s Qur’an memorisation section, even if it is charitable work.

	But if he gave it as a waqf to the institute in general, then 
	it may be used for anything having to do with the interests of this 
	institute, including transporting its students to pray Taraweeh in other 
	mosques.

	It says in al-Mawsoo‘ah al-Fiqhiyyah (6/307):

	If the one who gives a waqf stipulates conditions governing 
	the waqf, then the majority of scholars are of the view that reference 
	should be made to the conditions stipulated by the donor, because the 
	conditions mentioned by the donor of a waqf are what govern the ways in 
	which it is to benefit people; these conditions carry weight so long as they 
	are not contrary to sharee‘ah.

	Shaykh Ibn ‘Uthaymeen (may Allah have mercy on him) said:

	It is obligatory to act in accordance with the conditions 
	stipulated by the donor of the waqf… i.e., what was stipulated in terms of 
	description, restrictions or the absence thereof, users and so on. Reference 
	should not be made to the opinion of the supervisor regarding that; rather 
	reference should be made to what was stipulated by the one who set up the 
	waqf, and his conditions should be adhered to, unless they are contrary to 
	sharee‘ah.

	Shaykh Ibn Jibreen (may Allah have mercy on him) was asked:

	Is it permissible to use cars belonging to charitable 
	organisations for one’s personal business?

	He replied:

	That is not permissible, because they are a waqf given to the 
	organisation for the purpose of charitable work done by that organisation. 
	So the worker does not have the right to use them for his own affairs, 
	unless they were given to those who are in need, and the description of 
	those to whom the waqf was given is applicable to him, whether that is on a 
	permanent basis or in specific situations only.

	And Allah knows best.
