Is it obligatory to respond to one who asks in the name of Allah?

Question:
What is the ruling on one who asks in the name of Allah for a matter and is not answered? And what is the ruling on one who is asked in the name of Allah and does not act?

Answer:
The Prophet (peace and blessings be upon him) said: except if he has a right in what he asked for. Even if he said, "I ask you by Allah to give me from the zakah," and he is not among those entitled to zakah, he is not given. But if he asks for something in which he has a doubt: he asks from the public treasury, or asks to be given because he is poor, he is given what is available: whoever asks in the name of Allah, give to him. But it is not befitting to ask in the name of Allah; do not press people; for this reason, the angel who came to the leper, the blind man, and the bald man said: (I ask you by the One who gave you such and such), he asked by Allah.
The point is that if it is in something important and he asks in the name of Allah; he is given if he has a right. As for if he has no right, he is not given even if he asks in the name of Allah. So if he said, "I ask you by Allah to give me from the zakah," and he is not among those entitled to it; he is not given from the zakah; because he is not among those entitled to it. Or if he said, "I ask you by Allah to give me your wealth and everything you have and leave nothing for yourselves," he is not given.
