Abu Huraira (may Allah be pleased with him) narrated from the Prophet (peace and blessings of Allah be upon him) that the night (‘Isha) and dawn (Fajr) prayers are heaviest upon the hypocrites among all the prayers, and the Prophet (peace and blessings of Allah be upon him) said: If only they knew what reward there is in the night (‘Isha) and dawn (Fajr) prayers. Abu ‘Abdullah (Imam Bukhari, may Allah have mercy on him) says that it is better to say“‘Isha,”because the command of Allah is «ومن بعد صلاة العشاء‏» (in the Qur’an, it is named ‘Isha). Abu Musa al-Ash‘ari (may Allah be pleased with him) narrated that we used to take turns to pray the ‘Isha prayer in the mosque of the Prophet (peace and blessings of Allah be upon him). Once, he prayed it late at night. And Ibn ‘Abbas (may Allah be pleased with them both) and ‘A’isha (may Allah be pleased with her) reported that the Prophet (peace and blessings of Allah be upon him) prayed the ‘Isha prayer late. Some narrated from ‘A’isha (may Allah be pleased with her) that the Prophet (peace and blessings of Allah be upon him) prayed «عتمه» late. Jabir (may Allah be pleased with him) said that the Prophet (peace and blessings of Allah be upon him) used to pray“‘Isha.”Abu Barzah al-Aslami (may Allah be pleased with him) said that the Prophet (peace and blessings of Allah be upon him) would delay the ‘Isha prayer. Anas (may Allah be pleased with him) said that the Prophet (peace and blessings of Allah be upon him) used to pray the last ‘Isha late. Ibn ‘Umar, Abu Ayyub, and Ibn ‘Abbas (may Allah be pleased with them) said that the Prophet (peace and blessings of Allah be upon him) prayed Maghrib and ‘Isha.

Narrated `Abdullah: "One night Allah's Apostle led us in the `Isha' prayer and that is the one called Al-`Atma [??] by the people. After the completion of the prayer, he faced us and said, "Do you know the importance of this night? Nobody present on the surface of the earth tonight will be living after one hundred years from this night." (See Hadith No. 575).
