Can we buy stuff (e.g., clothes, kids’ toys, things for home décor) for ourselves during the months of Muharram and Safar or is that prohibited?
There is no problem with shopping during Muharram and Safar. A person should differentiate between religious rules and culture. However, it would be an issue if such purchases somehow gave the impression of association with Umayyid happiness/celebration over killing Imam Hussain (p).
