What did the Prophet Muhammad (peace be upon him) do when he saw the people assembled for the 'Isha' prayer?
 Narrated Jabir bin `Abdullah:                     The Prophet used to pray the Zuhr at midday, and the `Asr at a time when the sun was still bright, the Maghrib after sunset (at its stated time) and the `Isha at a variable time. Whenever he saw the people assembled (for `Isha' prayer) he would pray earlier and if the people delayed, he would delay the prayer. And they or the Prophet used to offer the Fajr Prayers when it still dark.
