Ibn 'Umar reported Allah's Messenger ﷺ as saying: When the rim of the sun starts appearing defer prayer till it completely appears, and when the rim of the sun disappears defer prayer till it completely disappears.
The Prophet Muhammad's teachings on prayer remind us that we must be mindful and careful in all aspects of our lives, including when we perform religious duties such as praying. We must take care to ensure that all aspects of our lives are done with intention and mindfulness so that we can reap the full benefits from them.
