Is contributing to the purchase of consumable goods for the mosque, such as furnishings, lighting and sound equipment, and air conditioning, considered the same as contributing to the construction of permanent structures, such as reinforced concrete and its coverings?

Continuous charity (Sadaqah Jariyah) has great merit, and its reward continues after death. This includes building mosques and maintaining them with their needs, such as carpets, lighting, sound systems, and air conditioning. Everything whose benefit lasts for a long time is better.
