قَالَ رَسُولُ اللهِ ﷺ: «أقْرَبُ مَا يَكُونُ الرَّبُّ مِنَ العَبْدِ، فِي جَوْفِ اللَّيْلِ الآخِرِ؛ فَإنْ اسْتَطَعْتَ أنْ تَكُونَ مِمَّنْ يَذْكُرُ اللهَ فِي تِلْكَ السَّاعَةِ؛ فَكُنْ»

The Messenger of Allāh \pbuh said : “The nearest the Lord comes to His servant is in the middle of the night, so if you are able to be of those who remember Allāh at that time, then be so.”
