Is it permissible to clip one's nails on Wednesday, and does it bring about poverty, and is it forbidden to remove hair from the anus?

Trimming nails is among the desirable practices of the fitra. There is no evidence that restricts its performance to a specific time or prohibits it at a particular time, such as Wednesday. The default ruling for it is permissibility. As for shaving hair around the anus, it is recommended when there is a need for it, such as its length. The preferred timing for this is determined by need, and it should not be left for more than forty nights.
