والصلاة في الأرض المغصوبة، والبيع في وقت النداء
Prayer on usurped land and trade during the restricted Friday call provide further applications.
Prayer has its own conditions while unlawful possession of the land is a separate wrong. A sale may have a recognizable transactional form while engaging in trade at the relevant call conflicts with the obligation of Friday prayer.
Conclusion: some legal effects of an act may coexist with a sin attached to it. At the same time, where independent conditions for validity are absent, these examples do not make the act valid automatically.
