Is the written assistance from the Syndicate for engineers with cancer considered a will, and is it forbidden to contest it, especially since it did not specify the names of the beneficiaries?

Scholars have differed regarding bequests to unspecified beneficiaries. The majority of scholars hold that such bequests are effective only for those who exist at the time of the testator's death, similar to inheritance. Some scholars, however, maintain that the existence of the unspecified beneficiary is not a condition, neither at the time of the bequest nor at the time of the testator's death, and they have validated bequests to non-existent entities, by analogy with endowments (waqf).

It appears that the view of the majority is stronger, because the purpose of a bequest is a specific, existing recipient, unlike an endowment, which is intended for permanence. Therefore, the woman's bequest to engineers afflicted with cancer is effective for those existing at the time of her death, and it should not be challenged.

It is important to note that charitable aid for the deceased's family after their death is not considered part of a bequest. Furthermore, a bequest is only effective up to one-third of the estate; anything exceeding this amount depends on the heirs' approval. It is advisable to consult the Sharia court regarding inheritance matters.
