Then when they have performed (their) prostrations...
Then when they have performed (their) prostrations, let them (continue the second unit solitarily and) take their precaution in your rear, and let another party who have not prayed come and pray with you (from the second unit), and let them take their precautions and their arms; (for) those who disbelieve desire that you should be heedless of your weapons and your baggage, then they would attack you all at once…." Thus, in no condition prayer can be dropped and never a striver is without establishing prayer.
There must be weapon in one hand and spirituality in the other. For the importance of the congregation prayer mentioning only this fact is enough that, when facing the enemy in the battle-field, even one unit of the prayer is to be established either. It should also be noticed that when two duties come forth with together (i.e. holy struggle and prayer) one must not be sacrificed for the other. By the way, self-consciousness is always necessary.
Even at the time of establishing prayer, Muslims should not be neglectful of the danger of the enemy. So, in no circumstances a striver must be in distance with the protective means. (If he has not any weapon, he should wear armour). It is for the caution that if the enemy attacks he can protect himself until the help comes.
"Then when you have finished the prayer, remember Allah standing and sitting and reclining. Then, when you are secure, (from danger) establish the prayer (as usual). Verily the prayer, at fixed times has been enjoined upon the believers." The Importance of Prayers, a Commandment!
