Puberty is the condition of the applicability of law but not that of the validity of an act. A minor is not himself obligated to observe the precepts of religion, but if he is possessed of enough understanding and can perform a religious act correctly like an adult, his act will be valid. As such in a congregational prayer a child can be an intermediary between the imam and the mamums or between the various sections of the mamums. He can also perform acts of worship on behalf of others.
The fact that puberty is not a condition of the validity of the acts of worship is indisputable. But what about transactions? Some Ulema are of the view that puberty is the condition of the validity of transactions also, and as such even a boy possessed of full understanding cannot independently carry out a transaction, neither for himself nor on behalf of anyone else. For example, a minor cannot sell, purchase or let anything nor can he pronounce the marriage formula.
Some other Ulema hold that a boy possessed of understanding cannot carry out a transaction independently for himself, but he can serve as an agent of others. Knowledge and awareness and similarly non-compulsion by the force of circumstances are the conditions of the applicability of law but not that of validity. As such, if a person unconsciously performs an act, whether it is an act of worship or it is a transaction, it will be valid if it is by chance perfect in all other respects.
Similarly if a man is compelled by force of circumstances to carry out a transaction or a marriage contract, it will be valid. For an example, there is a man who owns a house which he likes very much and is not interested at all in selling it. But all of a sudden for some reason or other he gets badly in need of money and is forced to sell it. In this case his transaction is valid. Take another example. A man or a woman is not in any way inclined to marry.
But a disease so develops that the physician advises that man or woman to marry immediately and thus he or she is forced to do so. This marriage is also valid. This shows that from the viewpoint of validity there is a difference between a transaction carried out under duress and a transaction forced by circumstances. The former is not valid, but the latter is.
Here it appears to be necessary to explain why a transaction entered into under duress is not valid and a transaction forced by circumstances is valid.
