What is the ruling on designating charity specifically for Monday for school students?

Question:
May Allah reward you, Honorable Shaykh. This questioner says: Recently, some Quran memorization centers have started placing a box labeled "Monday Charity." Charity is placed in this box every Monday, and the students and teachers, both male and female, are obligated to do so, along with a collective iftar (breaking of the fast) every Monday. Is this action valid?

Answer:
By Allah, we fear that bid'ah (religious innovations) and ideas will seep into our children in these matters, so one must be cautious regarding such things. First, who designated charity specifically for Monday? Second, where does this money go and how is it spent? We do not know. The obligatory thing is to be cautious in these matters. These are classes for teaching the Quran only; they are not classes for collecting money. They are for teaching the Quran only, and the teachers are paid their salaries and rewards by the association. There is no need to collect from the students. Yes.
