Perform prayers on time; Make exceptions during times of need or travel; Strive to perform ablutions before prayer whenever possible .

This hadith is about the Prophet Muhammad's journey with his companions to Khaibar. During their journey, they stopped at a place called As-Sahba' and when it was time for prayer, there was no food available except for sawiq. The Prophet Muhammad ate some of it and then performed the Maghrib prayer without performing ablution again after eating the sawiq. This hadith teaches us that in certain situations, such as when travelling or in times of need, we can eat food without performing ablution beforehand or afterwards. It also shows us that even though we are allowed to do this in certain circumstances, we should still strive to perform ablutions before praying whenever possible.
