Is it permissible to pick fruits from the mosque garden in exchange for placing a sum of money in the mosque's treasury?

The majority of jurists dislike planting trees in the mosque, and some of them have gone further to prohibit it if it restricts the worshippers, or brings impurities, or resembles churches. For the mosque was built for the remembrance of Allah and prayer, not for planting trees.

However, if the trees were planted before the construction of the mosque, or in an attached garden that does not harm the worshippers, then there is no objection.

As for eating from the fruits of these trees: 1. If the endower specified the use of the fruits, then their specification must be followed. 2. If the endower did not specify the use, then there is a difference of opinion: some said it belongs to the endower or their heirs, some said it belongs to the poor of the mosque, and some said it should be spent on the mosque's interests. 3. What is planted in the mosque without being endowed with it: If it was planted for the mosque, then nothing should be taken from it except for compensation that is spent on the mosque's interests. If it was planted as a general endowment (sabil), then it is permissible to eat from it without compensation, but refraining from eating is preferable.
