سنن النسائي

It was narrated that 'Abdullah bin Mas'ud said: "We were with the Messenger of Allah (ﷺ) and we were prevented from praying Zuhr, 'Asr, Maghrib and 'Isha'. I felt very upset about that and I said to myself: 'We are with the Messenger of Allah (ﷺ) and (fighting) for the sake of Allah.' Then the Messenger of Allah (ﷺ) commanded Bilal to say the Iqamah and he led us in praying Zuhr. Then he said the Iqamah and he led us in praying 'Asr. Then he said the Iqamah and he led us in praying Maghrib. Then he said the Iqamah and he led us in praying 'Isha'. Then he went around among us and told us: 'There is no group on Earth who is remembering Allah, the Mighty and Sublime, except you.'"
