If a person delays prayer

If a person delays prayer until the athan for the next prayer is called, upon entering the masjid, what should the person do? Answer: If there is enough time, for example between the athan and the iqamah, the person should pray the prayer he delayed. But if there is not enough time, then he should pray the prayer that is being established during that time, and thereafter pray what he delayed in performing. (Sheikh Saleh As Suhaymee)
