Delay your prayer when you see a part of sun on horizon

The Prophet Muhammad (PBUH) taught us that when the sun is rising or setting, we should wait until it has completely come into view before we start our prayers. This means that if we can see even a small part of the sun on the horizon then we should wait until it has fully risen or set before beginning our prayers. This teaches us to be patient and mindful of Allah's commands even in something as simple as prayer. It also reminds us to be aware of our surroundings and take note of what time it is so that we can pray at its proper time.
