685. Whenever the time left for offering prayer is so constrained that should one perform wuÃÙ or ghusl, he would have to offer his entire prayer or a part of it outside the allocated time, he should perform tayammum instead, unless the time it takes to perform ghusl or wuÃÙ is the same as the time it takes to perform tayammum, in which case he should perform wuÃÙ or ghusl.
686. If a person delays offering his prayer to such a time that he does not have enough time to perform wuÃÙ or ghusl, he will have committed a sin. However, the prayer that he offers with tayammum is in order. The recommended precaution is that he should also offer its qaÃÁ with wuÃÙ or ghusl.
687. If a person doubts that were he to perform wuÃÙ or ghusl, he may not have enough time to offer his prayer, such a person should perform tayammum.
688. If a person performs tayammum due to time constraints, and after offering his prayer is able to perform wuÃÙ, but fails to do so until water is no longer available to him, should his duty be to perform tayammum, he should perform tayammum once again for the subsequent prayer.
689. If a person who possesses water offers his prayer with tayammum due to time constraints, and in the midst of his prayer loses the water, recommended precaution dictates that should his duty be to perform tayammum, he should perform tayammum once again for the subsequent prayer.
690. If a person has enough time to perform wuÃÙ or ghusl, and offer his prayer without performing the recommended acts, such as iqÁmah and qunÙt, he should perform wuÃÙ or ghusl and offer his prayer without the recommended acts. In fact, should he not have enough time to recite the second sÙrah, he should perform ghusl or wuÃÙ and offer his prayer with the latter sÙrah.
