ANSWER: Small quantities of water, such as one cupful, or even two or three, must be considered used after a single washing of the face and hands. But a kurr(19) or more of water remaineth unchanged after one or two washings of the face, and there is no objection to its use unless it is altered in one of the three ways,(20) for example its colour is changed, in which case it should be looked upon as used. 92. QUESTION: In a treatise in Persian on various questions, the age of maturity hath been set at fifteen; is marriage likewise conditional upon the reaching of maturity, or is it permissible before that time? ANSWER: Since the consent of both parties is required in the Book of God, and since, before maturity, their consent or lack of it cannot be ascertained, marriage is therefore conditional upon reaching the age of maturity, and is not permissible before that time. 93. QUESTION: Concerning fasting and obligatory prayer by the sick. ANSWER: In truth, I say that obligatory prayer and fasting occupy an exalted station in the sight of God. It is, however, in a state of health that their virtue can be realized. In time of ill-health it is not permissible to observe these obligations; such hath been the bidding of the Lord, exalted be His glory, at all times. Blessed be such men and women as pay heed, and observe His precepts. All praise be unto God, He who hath sent down the verses and is the Revealer of undoubted proofs! 94. QUESTION: Concerning mosques, chapels and temples. ANSWER: Whatever hath been constructed for the worship of the one true God, such as mosques, chapels and temples, must not be used for any purpose other than the commemoration of His Name. This is an ordinance of God, and he who violateth it is verily of those who have transgressed. No harm attacheth to the builder, for he hath performed his deed for the sake of God, and hath received and will continue to receive his just reward. 95. QUESTION: Regarding the appointments of a place of business, which are needed for carrying on one’s work or profession: are they subject to the payment of Ḥuqúqu’lláh, or are they covered by the same ruling as the household furnishings? ANSWER: They are covered by the same ruling as the household furnishings. 96. QUESTION: Concerning the exchange of property held in trust for cash or other forms of property, to guard against depreciation or loss. ANSWER: Regarding the written question on the exchange of property held in trust to guard against depreciation and loss, such exchange is permissible on condition that the substitute will be equivalent in value. Thy Lord, verily, is the Expounder, the Omniscient, and He, truly, is the Ordainer, the Ancient of Days. 97. QUESTION: Concerning the washing of the feet in winter and summer.
