Remembrance of Allaah
A tafseer of Surah Al-A'raf verse 205
QUR'AN
﷽
وَٱذْكُر رَّبَّكَ فِى نَفْسِكَ تَضَرُّعًۭا وَخِيفَةًۭ وَدُونَ ٱلْجَهْرِ مِنَ ٱلْقَوْلِ بِٱلْغُدُوِّ وَٱلْـَٔاصَالِ وَلَا تَكُن مِّنَ ٱلْغَـٰفِلِينَ
And remember your Lord within yourself, humbly and with fear and without loudness in words in the mornings, and in the afternoons and be not of those who are neglectful
al-A'râf vs 205
Remembering Allāh سبحانه و تعالى may be done in the heart or verbally, or it may be both, which is the most perfect kind of dhikr, Allāh enjoined His slave and Messenger Muhammad (ﷺ) first of all, and others by virtue of their following him, to remember his Lord to himself that is sincerely when he is alone.
[with humility] that is, beseeching verbally, repeating all kinds of dhikr (remembrance)
[and reverence] in your heart, with fear of Allāh and apprehension that your deed may not be accepted. The sign of fear of Allāh is that one strives and does one's utmost to perfect one's deeds, try to improve on them and be sincere.
[without raising your voice] that is, be moderate, neither too loud nor too quiet in your prayer, but following a middle course.
[in the morning] at the beginning of the day
[and in the evening] at the end of the day. The advantage and virtue of remembering Allāh at these two times is greater than at others.
[and do not be among the heedless], those who forget Allāh, so He causes them to forget themselves; thus they are deprived of good in this world and the hereafter. They turn away from all blessings and success that come from remembering Him and submitting oneself in servitude to Him, and they turn to and focus on all that leads to misery and doom.
This is the etiquette to which the individual should pay proper attention, namely remembering Allāh a great deal throughout the night and day, especially at the two ends of the day, sincerely, with proper focus and humility, and calmly, focusing on what one says, with proper conduct and dignity, calling upon Allāh and remembering Him with full presence of mind, and not being heedless, for Allāh does not answer the supplication of one who is distracted and not focused on what he saying.
