Sayyiduna Anas bin Malik (RA) narrates that the iqamah for the ‘Isha prayer was pronounced or one night the ‘Isha prayer was delayed, then a man stood up and said: O Messenger of Allah! I have some work with you. So the Prophet (peace and blessings be upon him) began to whisper with him until the people started to fall asleep, then the Prophet (peace and blessings be upon him) led the prayer and no mention of ablution was made.
