عَنْ جَابِرِ بْنِ عَبْدِ اللَّهِ رَضِيَ اللَّهُ عَنْهُ قَالَ: جَهَّزَ رَسُولُ اللَّهِ صَلَّى اللَّهُ عَلَيْهِ وَآلِهِ وَسَلَّمَ جَيْشًا لَيْلَةً حَتَّى ذَهَبَ نِصْفُ اللَّيْلِ أَوْ بَلَغَ ذَلِكَ ثُمَّ خَرَجَ فَقَالَ: ((قَدْ صَلَّى النَّاسُ وَرَقَدُوا وَأَنْتُمْ تَنْتَظِرُونَ هَٰذِهِ الصَّلَاةَ، أَمَّا إِنَّكُمْ فِي صَلَاةٍ مَا انْتَظَرْتُمُوهَا))
Sayyiduna Jabir bin Abdullah (ra) narrates that the Messenger of Allah (peace and blessings be upon him) prepared an army one night, until half the night had passed. Then he (peace and blessings be upon him) came out and said: Indeed, other people have prayed and gone to sleep, and you are waiting for this ‘Isha prayer. Beware! Surely, from the time you have been waiting for this prayer, you have been in prayer itself.
