” Why do some of each group among them is not going to deepen knowledge of the religion (Islam) to (then) give a warning to his people when they have returned so that they can keep him.” (Surat at-Tawbah : 122).
In connection with this paragraph the Prophet SAW said, “(To) those that God really wants to get good, He will grant him a depth of knowledge in the religion (Islam).” (Bukhari and Muslim).
Muslims who already have knowledge in the religion (Islam) has the task of distributing them orally or in writing. In this connection, there are a number of verses that encourage Muslims who already have knowledge in the religion (Islam) to divide it orally or in writing to the others of which appear in Surah at-Tawbah : 122.
A hadith of the Prophet Muhammad said, “If a man dies then all his deeds will be disconnected unless three things, charity jariah or useful science or pious child who (always) prays.” (Muslim, Tirmidhi, Abu Dawud, Nasa’i, and Ahmad).
In another hadith the Prophet said, “The most valuable charity is if there is a Muslim studying, then he taught it to other Muslim brothers.” (Reported by Ibn Majah).
However, people ordered to do right and forbid doing unjust to others he should already practicing it himself. Because if not the punishment is very hard. Allah says, ” Great is hatred in the sight of Allah that you say what you do not do.” (Surah Ash-Shaff : 3).
Rasulullah SAW said, “On the Day of Judgment, two feet of a servant will not be able to move, before you ask: ‘what did your knowledge use for?'” (Tirmidhi). Usamah bin Zaid RA said, I have heard Rasulullah SAW said, “On the Day of Judgment, someone come. Then he put in a hell in a state of his bowels gushed out. Then in hell he circled like a spinning-swivel donkey tied with pestle wheat”
“The inhabitants of hell crowding then asked the man, ‘what happened to you, O Fulan? For you were telling us to do right and forbids us to do wrong? ‘The person said:’ Yes, I once told you to do kindness but I never did it. I once prohibited you do something wrong but I myself did it ‘. “(Bukhari and Muslim).
Prophet also said, “At night in Isra moment, I saw a group of people whose lips were cut with scissors made of fire. I asked Gabriel: ‘Who are they?’ Gabriel replied: ‘They are your people who become preachers they say what do not they do.’ “(Ahmad).
