Salatul tahajjud (late-night prayer) during one of its nights is like performing the late night prayer on the night of power

Bismillahir Rahmanir Rahim

In the name of Allah, the Most Beneficent, the Most Merciful

Abu Hurairah relates that the Messenger of Allaah (sallallaahu 'alaihi wa sallam) said,

"There are no days more loved to Allaah for you to worship Him therein than the ten days of Dhul Hijja. Fasting any day during it is equivalent to fasting one year and to offer salatul tahajjud (late-night prayer) during one of its nights is like performing the late night prayer on the night of power. [i.e., Lailatul Qadr]."

[This is related by at-Tirmidhi, Ibn Majah, and al-Baihaqi]

The Prophet sal Allahu alayhi wa'sallam said:

"The Muslim is a unique Ummah among the whole of mankind:
Their Land is ONE, their War is ONE, their Peace is ONE,
Their Honour is ONE and their Trust is ONE."
