"The idolaters kept Allah's Messenger distracted from four prayers on the Day of Al-Khandaq (the battle of the Trench) until as much as Allah willed of the night had passed. So he ordered Bilal to call the Adhan, then he called the Iqamah to Zuhr, then he called the Iqamah to pray Asr, then he called the Iqamah to pray Maghrib, then he called the Iqamah to pray Isha."
