Is it permissible to place religious papers or currency that contain the word "Allah" in the back pocket of trousers without a wallet?

If the back pocket is clean and the papers containing religious texts are not subjected to desecration by sitting on them, then there is no harm in putting them there. However, if they are exposed to desecration by sitting on them or by any other means, then it is not permissible to put them there, as this contradicts the veneration of the sacred things of Allah.
