It is narrated from Hazrat Abu Huraira (may Allah be pleased with him) that the Noble Prophet (peace and blessings be upon him) said: If I did not fear hardship for my ummah, I would have ordered them to use the miswak at the time of every prayer and to delay the Isha prayer until one third or half of the night had passed.
