The endowment is the withholding of money that can be used while keeping its original amount of money and spending its revenues on an existing permissible bank (spending channel).

As for the donation, it is the donor giving money or benefit to others immediately or later without compensation with intention of righteousness and good deed. The donation has many forms, including charity, gift, will, loan, endowment, and sponsorship.

It is clear from the previous definitions that the difference between the donation and the endowment is that the money at the origin of the donation may perish and end while in the endowment it is permanent and does not cease. This leads us to the fact that the benefit of the endowment is permanent, while the benefit of the donation may be eliminated by the loss of the original, and the endowment is considered a form of donation, so the donation includes the endowment and other forms.​
