#wakeup O servant of Allah @WakenwakeOthers ​

At night when the night sleeps, Allah asks for people if they want anything so Allah shell bless him/her with it. According to Aalims, it the time after 2am.
There are several narrations attributed to the Prophet Muhammad (PBUH) regarding the virtues and benefits of Tahajjud prayer. Here are a few examples:
1: "The best prayer after the obligatory prayers is the night prayer." (Sahih Muslim)

2: "The most beloved prayer to Allah is the prayer of Dawud (Prophet David). He would sleep for half of the night, then get up and pray for a third of the night, and sleep for a sixth of the night." (Sahih Bukhari)

3: "Whoever prays during the night, reciting ten verses, will not be recorded as one of the heedless, and whoever prays during the night, reciting a hundred verses, will be recorded as one of the devout, and whoever prays during the night, reciting one thousand verses, will be recorded as one of the muqantareen (those who pile up good deeds)." (Abu Dawood)
