Hazrat Abu Ishaq narrates that a beggar asked Hazrat Abdullah bin Umar (may Allah be pleased with them), Hazrat Hasan, Hazrat Husain, and Hazrat Abdullah bin Ja'far a question. All of them said to him: If you are asking because you have a terrifying and severe debt, or extreme poverty, or you have to pay blood money and will be killed otherwise, then it is permissible for you to ask (and otherwise, it is not).
