Is it permissible for employees of the Holy Quran Memorization Department—whose salaries are paid from endowment funds—to continue receiving their salaries when traveling for tasks unrelated to their original work, or when ill with a medical certificate, or when taking an annual paid monthly leave, or during official state holidays? And to what extent does the supervisor of the endowment have the authority to dispose of endowment funds based on state laws and common custom, in cases where the endower did not specify these matters?

It is permissible for the supervisor to deviate from the endower's condition if there is a religious benefit in doing so, such as allocating the endowment for jihad when needed, or for maintaining the حرم (sacred precinct), while taking into account the general intent of the endower. This is supported by the statement of Ibn Taymiyyah: "It is permissible to change the endower's condition to one that is more beneficial, even if that varies with the change of times." Furthermore, custom determines how endowment funds are to be managed if no specific conditions were stipulated by the endower. Based on this, it is permissible to grant annual and sick leaves to employees in Quran memorization departments, and to assign them to other tasks if this is customary, provided that it serves a religious benefit and is not merely for personal whims.
