There are two important subjects in this lesson; first, knowledge, second, zikr (that is, remembrance of Allah).
There are so many sayings of Rasulullah (Sallallahu alaihi wasallam) which stress the utility and distinction of these two things. For instance, a hadith says, “Beware! This world, and whatever is in it, is cursed by Allah, with the exception of prayers, and zikr, and the religious scholar, and the religious student”.
Therefore, every Muslim should try his best to achieve the high standard of knowledge and zikr.
Knowledge
“Verily, the worst punishment of Allah will be inflicted on those on the Day of Judgement, who have been scholars of religion, but did not practice it themselves”.
The distinction of a scholar and a student
Another hadith says, “A thousand worshippers are not so annoying and deadly to Shaytaan, as one person who has achieved perfect knowledge about Islam”.
Another hadith says, “Anyone who died during the period of attaining knowledge about Islam, his class in Jannah will be only one stage below the Ambiyaa”.
Another hadith says, “The best person among you is he, who has learned the Holy Qur’an and then teaches it to other Muslims”.
Rasulullah (Sallallahu alaihi wasallam) says in another hadith, “May Allah keep that person fresh and healthy who listens to my instructions, and then delivers them to others, exactly as I have spoken”.
To leave home for the sake of knowledge
Rasulullah (Sallallahu alaihi wasallam) has said, “Whoever left his home for the sake of knowledge (about the Holy Qur’an and Islam), he will be honoured as one, who has entirely devoted himself to Allah”.
The service and help for a student of Islam
That is, when the student of Islam visit you, serve them properly, sit in their society, and be courteous to them.
The use of scholarly meetings
Rasulullah (Sallallahu alaihi wasallam) says in a hadith, “When certain people gather together in the House of Allah (that is a musjid), and they read the Book of Allah (i.e., the Holy Qur’an) to one another, they are blessed with spiritual consolation and Allah’s mercy, the Angels assemble around them, and Allah remembers them among His courtiers (Angels)”.
Zikr
The second part of the third lesson is zikr. The highest degree of zikr is that a believer should be entirely devoted to Allah, and should never forget Him. This standard of zikr is achieved by constant spiritual exercise, and by continuous remembrance of Allah. Those who have realized the spiritual benefits of zikr, they do not neglect it for a single moment of their life. Rasulullah (Sallallahu alaihi wasallam) instructed a companion of his with the following words, “Keep your tongue always busy with the remembrance of Allah”.
In another hadith he says, “When some people gather together in an assembly, and then get up without remembering Allah, be sure that they sat around the dead body of an ass, and left it; therefore such an assembly will be a sorrow to them on the Day of Qiyaamah”.
The true believers should remember Allah most often, and by contemplating the wonders of His creation, they should glorify Him, and thereby strengthen their love for Him. The more they remember Allah, the better will be their good deeds, the stronger their faith and knowledge.
The preference of zikr
It has been mentioned in the hadith that zikr purifies and enlightens the heart. Another hadith says that nothing saves a Muslim from the chastisement of Allah, more than zikr. Another Hadith says that amongst the negligent, one who remembers Allah most often is like a glowing lamp in a dark house. A hadith of Bukhaari says, “One who remembers Allah, is remembered by Him among His courtiers (Angels)”.
Rasulullah (Sallallahu alaihi wasallam) in another hadith says, “Anyone who remembers Allah most often is so much preferable to a person, who distributes a great amount of money in the way of Allah”. (Targheeb)
