Sermon (238): He told his companions to prepare for war and avoid seeking rest

God the Almighty demands gratitude from you and has made you the owner of His power and has given you respite in this limited field (of life) so that you strive to surpass each other in obtaining the reward of excellence. Tighten the waist and turn the skirt. High courage and desire for feasts cannot go together. Deep sleep at night is very debilitating in the campaigns of the day, and (its) darkness is very obliterating to the memory of courage.
