The Virtue of remembering Allah much
Allah commands;
يَا أَيُّهَا الَّذِينَ امَنُوا اذْكُرُوا اللَّهَ ذِكْرًا كَثِيرًا
O you who believe!
Remember Allah with much remembrance.
Allah commands His believing servants to remember their Lord much, Who has bestowed upon them all kinds of blessings and favors, because this will bring them a great reward and a wonderful destiny.
Imam Ahmad recorded that Abdullah bin Busr said;
"Two Bedouins came to the Messenger of Allah and one of them said;`O Messenger of Allah, which of the people is best'
He said;
مَنْ طَالَ عُمْرُهُ وَحَسُنَ عَمَلُه
The one whose life is long and whose deeds are good.
The other one said;`O Messenger of Allah, the laws of Islam are too much for us. Teach me something that I can adhere to.'
He said,
لَاايَزَالُ لِسَانُكَ رَطْبًا بِذِكْرِ اللهِ تَعَالَى
Keep your tongue moist with the remembrance of Allah, may He be exalted.
At-Tirmidhi and Ibn Majah recorded the second part of this report.
At-Tirmidhi said, "This Hadith is Hasan Gharib".
Imam Ahmad recorded that Abdullah bin `Amr, may Allah be pleased with him, said that the Messenger of Allah said,
مَا مِنْ قَوْمٍ جَلَسُوا مَجْلِسًا لَمْ يَذْكُرُوا اللهَ تَعَالَى فِيهِ إِلاَّ رَأَوْهُ حَسْرَةً يَوْمَ الْقِيَامَة
No people sit together without mentioning Allah, but they will see that as regret on the Day of Resurrection.
Ali bin Abi Talhah reported that Ibn Abbas, may Allah be pleased with him, commented on the Ayah;
اذْكُرُوا اللَّهَ ذِكْرًا كَثِيرًا
(Remember Allah with much remembrance),
"Allah did not enjoin any duty upon His servants without setting known limits and accepting the excuses of those who have a valid excuse -- apart from Dhikr, for Allah has not set any limits for it, and no one has any excuse for not remembering Allah unless he is oppressed and forced to neglect it.
Allah says;
فَاذْكُرُواْ اللَّهَ قِيَـماً وَقُعُوداً وَعَلَى جُنُوبِكُمْ
Remember Allah standing, sitting down, and (lying down) on your sides. (4;103)
By night and by day, on land and on sea, when traveling and when staying home, in richness and in poverty, in sickness and in health, in secret and openly, in all situations and circumstances.
And Allah says;
وَسَبِّحُوهُ بُكْرَةً وَأَصِيلً
