The Fifth Characteristic
وَالَّذِينَ يَقُولُونَ رَبَّنَا اصْرِفْ عَنَّا عَذَابَ جَهَنَّمَ (and those who say, "Our Lord, avert from us the punishment of Jahannam - Al-Furqan 25:65 ⧉). It means that despite their constant prayers day and night, these favoured ones do not sit content, but are always fearful of God and keep in mind the Day of Judgment. To that end they keep alive the righteous deeds as well as supplications before Allah.
