To live in the world we need to think. To live in Heaven requires remembrance. And we are so busy with thinking that we forget to dhikr.
So if time has passed and we forget to remember Allah at that time, immediately awaken your heart even if only with the words of prayer and forgiveness.
Neglect is a disease, and dhikr of Allah is a remedy for negligence of the heart. Shaykh Azhar, Shaykh Ahmad Thayyib Hafizahullah
