Allah -azwj has made Jihad (fighting for the cause of Allah)...

Allah -azwj has made Jihad (fighting for the cause of Allah) obligatory on the Muslims. Then the Messenger of Allah -saww increased the number of Rak’ats of Salat by seven Rak ‘ats. He increased two Rak’at with al-Zuhr, two with al-‘Asr, one with al-Maghrib, two with ‘Isha’ and left the morning Salat (prayer) as it was because of the quicker coming of the angels of the day from the sky and the ascending of the angels of the night to the sky.

The angels of the day and the angels of the night attended the morning Salat (prayer) with the Messenger of Allah -saww and for this reason Allah -azwj has said: ‘ … the reading at dawn, because the reading at dawn is attended.’ (17:78) The Muslims attended as well as the angels of the day and the angels of the night.
