Travelling and Salaah

Q: A traveler entered his home town just as the athaan of maghrib was going.. He had not yet performed his Asr. When he makes the qadhaa of Asr should he perform 2 or 4 rakaats?

A: The Asr salaah became qadhaa when the Maghrib athaan went off, since Asr ends when sunsets. At that point the musaafir had already entered his home town and had become a muqeem. The Asr thus became qadhaa whilst he was a muqeem, hence he has to make qadhaa of 4 rakaats nor 2.
