His statement, “and the like,” includes, in the present day, such things as cars, so it is valid to endow them. The same applies to pens, because they are used while their substance remains. As for pens that are consumed, such as pencils, it may be said that the lead within them is like ink, and thus it is valid to endow them.

Yet it may be held valid, because their consumption is slight while their usefulness lasts a long time; they are not like food, such as dates, wheat, and the like.
Thus, this first condition comprises more than one condition: it must have a benefit, that benefit must be enduring, it must be specifically identified, and it must be usable while its substance remains. It is one condition that encompasses four conditions.

This condition requires further detail: if it is for a general cause, then
