Supplicating for Purely Worldly
Things During the Prayer
Question :
Is it permissible for us to supplicate during the prayer for purely worldly things? Also, is it better to supplicate after the prayer is completed, after the first Tashahhud, or while prostrating?
Answer:
It is not permissible to supplicate in prayer for purely worldly things, like the realization of lusts, more money, or a beautiful wife. But if one has a dire need among worldly matters that will help him in his religion, it is then permitted to ask for such things. For example, one may ask for a wife to protect himself from the unlawful, to have money so that he doesn't have to depend on people, and so on. And the Sunnah after the obligatory prayers is what is found reported about statements of remembrance. There is no harm in supplicating after that with what is easy. And it is Sunnah to supplicate after the last Tashahhud and during the prostration, which is among the circumstances in which it is hoped it will be responded to. And Allah knows best.
