It could be only due to two things: One is that it could be that the object of the verb is eliminated that is ‘What do you order the soldiers?’ On the basis of this the word ‘order’ is used in its true sense as ‘I order’ with regard to the soldiers is more dignified. Secondly: Suppose they were higher and by way of metaphor – from one aspect – they are addressed in this way. And Allah knows best.
It is proved by this introduction that when the demand is issued from the Holy Prophet (S) in whatever word it be – even if it is interrogative, as mentioned in the captioned verse – it is an order, because sometimes allusion is made to question by way of humility which was the program of His Eminence and the basis of his words as he is reported to have said: “I have been sent for the perfection of morals.” Or it could be for moderation and kindness with the people so that they may accept his orders with sincerity and with seriousness; hence their position is supposed higher.
If we agree that the enforcement of Mawaddat is a part of: “I don’t ask you except the love of my kinsfolk.” It means that: My aim and desire that reverts to me is contained in it.
Obligatory nature of love can also be derived from another example and it is the statement of Allah, the Mighty and Sublime with the Holy Prophet (S) in which He says: ”Say: I don’t ask for anything.” As it shows that it is necessary for His Eminence to ask his right from them because if the fulfillment of this right had not been obligatory, he would not have asked them as is very much clear.
Second Introduction I made research into the principles of jurisprudence that the matter having implication is evident in inevitable demand, in other words demand is in fact, an order. That is: Except for the matter of demand nothing else is understood, and demand without specification of conditions, words or external in common parlance, its implication is on absolute demand and it is expressed in it.
The indication of this meaning is that we see commands that are issued by higher authorities to the lower, anyone who pays attention to them will not have any doubt that they are compulsory matters, rather it is in their nature that they will be impelled to perform what they are ordered and they have no hesitation whether these commands are compulsory or not.
