Perform voluntary prayer while travelling .

This hadith is about the importance of voluntary prayer while travelling. It was narrated by Yahya who heard it from Malik who in turn heard it from Nafi who reported that Abdullah Ibn Umar used to see his son Ubaydullah Ibn Abdullah doing voluntary prayers on a journey and he did not disapprove of it. This shows us the importance of performing voluntary prayers even when we are travelling and how our elders should encourage us to do so. It also teaches us the value of respecting our elders and their opinions as well as following their example in matters related to religion.
