The ruling on one who gives a sum of money to several people to perform 'Umrah on behalf of another!!

Question : The questioner says: A man wanted to perform 'Umrah on behalf of eight people, so he paid another man one thousand and two hundred riyals to carry out this task. The latter, in turn, paid eight hundred riyals to eight people, each of whom would perform 'Umrah on behalf of the people the first man had named. Among those named were Shaykh al-Islam Ibn Taymiyyah, Ibn al-Qayyim, and Muhammad ibn 'Abd al-Wahhab (may Allah have mercy on them). What is your answer to that?

Answer : Our answer to this is that, first, the apparent issue in the question is making one act of worship for eight people, meaning he says, "Labbaik (I am at your service) on behalf of so-and-so, so-and-so, and so-and-so," and lists eight people. This is not permissible. If a person did this, the act of worship would be for himself and would not be for any one of these eight. Likewise, if he intended it for more than one person, the act of worship would not be for more than one person. However, if he intends for eight people, meaning each person performs a separate act of worship, then there is nothing wrong with that. And if he dedicates the reward to one of the scholars, there is nothing wrong with that, but better than that is to make du'a' (supplication) for these scholars.
