750. A person can start offering prayers only when be becomes certain that the time has set in or when two just (Adil) persons inform that the time has set in. In fact, one can rely upon the Adhan, or on advice of a person who knows the timings and is reliable.
751. If a person cannot be certain about the Prime time for prayers due to clouds or dust or blindness or being in the prison cell, he should delay the prayer till such time when he feels sure that the time has set in.
753. If a person is heedless of the fact that he should pray after ensuring that the time has set in, and if he realises after the prayers that he had offered the entire prayers in time, his prayer is in order. And if he realises that he had offered his prayers before time or does not realise whether he had offered the prayers within time or not, his prayers will be void. In fact, if he realises after offering prayers that the time for prayers had set in while he was praying, he should offer that prayers again.
755. If the time left for Namaz is so little that if we perform some Mustahab acts of the prayers, an obligatory part of the prayers will fall beyond the prescribed time, one should not perform those Mustahab acts. For example, if on account of reciting qunut a part of the prayers will lapse beyond time, one should do without qunut.
756. If the time at the disposal of a person is sufficient for performing one Rak'at only he should offer the prayers with the Niyyat of Ada, i.e. offering the same in time. However, one should not delay offering prayers intentionally.
757. If a person who is not a traveller has at his disposal time for offering five Rak'ats till Magrib he should offer both Zuhr and Asr prayers. And if he has less time than that he should offer only Asr prayers, and thereafter he should give Qadha of Zuhr prayers. Similarly if he has sufficient time upto midnight for offering five Rak'ats, he should offer Maghrib and Isha prayers and if he has less time than that he should offer only Isha prayers and then offer the Qadha of Maghrib prayers.
759. It is Mustahab that a person should offer prayers at the Prime time prescribed for it, and great emphasis has been laid on it; alternatively, the nearer the prayers are to its Prime time, the better, except where there is good reason for delay, like, waiting to join the prayers in congregation (Namaz-e-Jamaat).
762. If there is ample time for prayers, and at the same time his creditor demands repayment of his loan from him, he should repay the loan first, if possible, and then offer prayers. Similarly, if there emerges another obligatory matter which demands immediate attention, like if a man sees that the Masjid is Najis he should make it Pak first and then offer prayers. And in both the cases if he offers his prayers first he commits a sin but his prayer is in order.
