Extracted from Dua's for the contentment of the Heart
When we look at this world we see beauty, grandeur, sublimity, strength, the power of joy or the power of destruction manifested in it. We are attracted or repulsed by these manifestations. We feel threatened by some or inspired by awe. There is an inevitable link between what we see and feel, and ourselves.
That link is provided by attributes of Allah. Each object manifests some power of Allah. His joy or His anger, His love or His magnificence emanates through these objects. There is no end to these manifestations so long as the process of creation exists.
The first man Adam (Alayhis Salaam) was taught the names of everything. Teaching the names means making man conscious of the essence of these things. This consciousness implies full knowledge. Full knowledge is impossible without the essence becoming part and parcel of the being. That is why Adam (Alayhis Salaam) could represent Allah as His Khalifa and become worthy of receiving the salutation of the angels. That is why Allah granted him and through him to man the mastery of this entire creation.
Allah, therefore, tells us to remember Him and draw near to Him by reciting His name or His attributes. Allah says:
ٱلَّذِينَ ءَامَنُوا۟ وَتَطْمَئِنُّ قُلُوبُهُم بِذِكْرِ ٱللَّهِ ۗ أَلَا بِذِكْرِ ٱللَّهِ تَطْمَئِنُّ ٱلْقُلُوبُ ٢٨
Those who believe and whose hearts find satisfaction in the remembrance of Allah: for without doubt in the remembrance of Allah do hearts find satisfaction. (Quran - Surah Ar-Ra'd - 13:28)
ٱتْلُ مَآ أُوحِىَ إِلَيْكَ مِنَ ٱلْكِتَـٰبِ وَأَقِمِ ٱلصَّلَوٰةَ ۖ إِنَّ ٱلصَّلَوٰةَ تَنْهَىٰ
عَنِ ٱلْفَحْشَآءِ وَٱلْمُنكَرِ ۗ وَلَذِكْرُ ٱللَّهِ أَكْبَرُ ۗ وَٱللَّهُ يَعْلَمُ مَا تَصْنَعُونَ ٤٥
Recite what has been revealed to you of the Book and establish prayer. Indeed, prayer prohibits immorality and wrongdoing, and the remembrance of Allah is greater. And Allah knows that which you do. (Quran - Surah Al-Ankabut - 29:45)
يَـٰٓأَيُّهَا ٱلَّذِينَ ءَامَنُوا۟ ٱذْكُرُوا۟ ٱللَّهَ ذِكْرًۭا كَثِيرًۭا ٤١
O' You who believe! Celebrate the praises of Allah, and do this often. (Quran - Surah Al-Ahzab - 33:41)
فَٱذْكُرُونِىٓ أَذْكُرْكُمْ وَٱشْكُرُوا۟ لِى وَلَا تَكْفُرُونِ ١٥٢
Therefore, remember Me and I will remember you; and be thankful unto Me and be you not ungrateful towards Me. (Quran - Surah Al-Baqarah - 2:152)
وَٱذْكُر رَّبَّكَ فِى نَفْسِكَ تَضَرُّعًۭا وَخِيفَةًۭ وَدُونَ ٱلْجَهْرِ مِنَ ٱلْقَوْلِ بِٱلْغُدُوِّ وَٱلْـَٔاصَالِ وَلَا تَكُن مِّنَ ٱلْغَـٰفِلِينَ ٢٠٥
And do you (O reader!) bring Your Lord to remembrance in your (very) soul with humility and in reverence, without loudness in words, in the mornings and evenings; and to be not you of those who are unheedful. (Quran - Surah Al-A'raf - 7:205)
The remembrance of Allah is the happiest and also the wisest of pastime. Its blessings can never be counted and the satisfaction it brings cannot be measured. It relieves one of worries that otherwise eat into one's heart and improves one's spiritual and worldly life.
Hadith narrated by Abu Huraira:
حَدَّثَنَا عَلِيُّ بْنُ عَبْدِ اللَّهِ، حَدَّثَنَا سُفْيَانُ، قَالَ حَفِظْنَاهُ مِنْ أَبِي الزِّنَادِ عَنِ الأَعْرَجِ، عَنْ أَبِي هُرَيْرَةَ،
رِوَايَةً قَالَ لِلَّهِ تِسْعَةٌ وَتِسْعُونَ اسْمًا، مِائَةٌ إِلاَّ وَاحِدًا، لاَ يَحْفَظُهَا أَحَدٌ إِلاَّ دَخَلَ الْجَنَّةَ، وَهْوَ وَتْرٌ يُحِبُّ الْوَتْرَ
Allah has ninety-nine Names, i.e., one hundred minus one, and whoever believes in their meanings and acts accordingly, will enter Paradise; and Allah is witr (one) and loves the witr (i.e. odd numbers). (Sahih al-Bukhari 6410 - Book 80, Hadith 105)
