Digital night vision is a technology that uses digital sensors and image processing algorithms to enhance low-light images and provide visibility in dark environments. Unlike traditional night vision devices that rely on intensifier tubes, digital night vision can capture and display images in real-time on a screen. This technology often offers features such as adjustable brightness, color modes, and the ability to record or capture images. Digital night vision devices are typically more compact, lightweight, and versatile compared to traditional night vision goggles. **

The white fast cloud in the night sky is most likely a cirrus cloud. Cirrus clouds are thin, wispy clouds that form at high altitudes and are made up of ice crystals. They often appear white and can move quickly across the sky due to the strong winds at high altitudes. These clouds are often associated with fair weather, but they can also indicate the approach of a change in the weather. **

A night light that shines all night is typically one that is plugged into an electrical outlet and has a built-in light sensor.

It is not necessary to perform Wudu every night before fasting. Wudu is only required before performing the five daily prayers, not before fasting. However, it is recommended to perform Wudu before Suhoor (pre-dawn meal) and before Fajr prayer, which marks the beginning of the fasting day. This is to ensure that one is in a state of purity before starting the fast. **
