Hisnul Muslim 251

Seeking forgiveness and repentance

وقال صلى الله عيه وسلم :" أقرب ما يكون الربُّ من العبد في جوف الليل الآخر فإن استطعت أن تكون ممن يذكر الله في تلك الساعة فكن"

The Prophet (SAW) said: "The closest that the Lord comes to the slave is in the last portion of the night. So, if you are able to be among those who remember Allah in this hour, then be among them".
