Is the strength of reliance on Allah the refusal to take means?

Question : Is the greatest aspect of reliance on Allah the refusal to take means?

Answer : No, my brother, taking means is part of the perfection of reliance on Allah. Abu Bakr (may Allah be pleased with him) used to give away all his wealth in the cause of Allah. The Messenger of Allah (peace and blessings be upon him) asked him what he had left for his family. Abu Bakr said, “I have left Allah and His Messenger.” This was the case with Abu Bakr; he did not neglect taking means because of the strength of his reliance on Allah (may Allah be pleased with him). He knew that Allah, Glorified and Exalted is He, would provide for him, because this is a provision that is gained through work, and he knew that Allah would not let him be lost. But if someone were to say, “I will sleep tonight in the coldest possible cold, on the roof, in a single garment, with my head, feet, and hands exposed, on the tiles,” and claim that he is relying on Allah so that the cold does not reach him, would that be permissible?
It is not permissible. For this reason, the Messenger of Allah (peace and blessings be upon him), the master of those who rely on Allah, would wear armor when in war, and at the Battle of Uhud he appeared between two armors, wearing two armors.
