• Among the lessons is that one begins, in the pursuit of knowledge, with what is most important and then proceeds to what is next; increasing one’s own knowledge takes precedence over foregoing that in order merely to teach, for a person learns so that he may teach.

• It is also permissible to take a servant along, whether on a journey or while residing at home, so as to cover provisions and enjoy some ease—just as Moses, peace be upon him, did.

• Another point: a traveller who sets out to seek knowledge, engage in jihad, or undertake any other journey of obedience—and even journeys beyond that—should, when benefit requires, make his purpose and destination known; this is better than concealing them. Public disclosure (1) enables him to gather the necessary supplies, (2) allows him to proceed with clear insight, and (3) openly encourages others toward that noble act of worship. Moses said: “I will not give up until I reach the junction of the two seas, even if it takes me years” (18:60). In the same way, when the Prophet—peace and blessings be upon him—marched to Tabuk, he informed the people of his objective, although he would usually veil his destination on other expeditions, each approach being chosen according to the benefit in the situation.

• Evil and its causes—as well as deficiency—are attributed to Satan, as in the words of Moses’ servant: “It was none but Satan who made me forget to mention it” (18:63).

• It is permissible for a person to state what he naturally experiences—fatigue, hunger, thirst—provided he is not complaining and speaks truthfully; witness the verse: “Indeed, we have met fatigue on this journey of ours” (18:62).

• Finally, one should choose a servant who is intelligent, alert, and resourceful so that his affairs may be properly accomplished.
