Appointing a leader when travelling
The Prophet (sal Allahu alaihi wa sallam) said, “When three persons set out on a journey, they should appoint one of them as their leader.”
[Sunan Abu Dawud]
We benefit from the above Hadith that It is mustahabb (recommended) for the group to appoint the best and wisest of their number as their leader, and to obey him.
Choosing anyone as leader means that a journey should be undertaken under his guidance and instructions. This has many benefits.
The person to be appointed as a leader over a group of travelers should fulfill certain important conditions, including the fact that he should be the most knowledgeable in religious matters and travelling conditions.
And Allah knows best!
