And Anas (may Allah be pleased with him) said that Uthman (may Allah be pleased with him) had copies of the Qur'an written and sent them to various regions. And according to Abdullah bin Umar (may Allah be pleased with them both), Yahya bin Sa'id, and Imam Malik (may Allah have mercy on him), this (writing) is permissible. And some people of Hijaz have deduced from the hadith of the Messenger of Allah (peace and blessings of Allah be upon him) regarding manawalah (handing over a written document), in which he wrote a letter for the commander of the army. Then he said (to the messenger), "Do not read this letter until you reach such-and-such a place." Then, when he reached that place, he read the letter before the people and informed them of the command of the Messenger of Allah (peace and blessings of Allah be upon him).

Narrated `Abdullah bin `Abbas: Once Allah's Apostle gave a letter to a person and ordered him to go and deliver it to the Governor of Bahrain. (He did so) and the Governor of Bahrain sent it to Chousroes, who read that letter and then tore it to pieces. (The sub-narrator (Ibn Shihab) thinks that Ibn Al-Musaiyab said that Allah's Apostle invoked Allah against them (saying), "May Allah tear them into pieces, and disperse them all totally.)"

Narrated Anas bin Malik: Once the Prophet wrote a letter or had an idea of writing a letter. The Prophet was told that they (rulers) would not read letters unless they were sealed. So the Prophet got a silver ring made with "Muhammad Allah's Apostle" engraved on it. As if I were just observing its white glitter in the hand of the Prophet.

Narrated Abu Waqid Al-Laithi: While Allah's Apostle was sitting in the mosque with some people, three men came. Two of them came in front of Allah's Apostle and the third one went away. The two persons kept on standing before Allah's Apostle for a while and then one of them found a place in the circle and sat there while the other sat behind the gathering, and the third one went away. When Allah's Apostle finished his preaching, he said, "Shall I tell you about these three persons? One of them betook himself to Allah, so Allah took him into His grace and mercy and accommodated him, the second felt shy from Allah, so Allah sheltered Him in His mercy (and did not punish him), while the third turned his face from Allah and went away, so Allah turned His face from him likewise. "

Narrated `Abdur-Rahman bin Abi Bakra's father: Once the Prophet was riding his camel and a man was holding its rein. The Prophet asked, "What is the day today?" We kept quiet, thinking that he might give that day another name. He said, "Isn't it the day of Nahr (slaughtering of the animals of sacrifice)" We replied, "Yes." He further asked, "Which month is this?" We again kept quiet, thinking that he might give it another name. Then he said, "Isn't it the month of Dhul-Hijja?" We replied, "Yes." He said, "Verily! Your blood, property and honor are sacred to one another (i.e. Muslims) like the sanctity of this day of yours, in this month of yours and in this city of yours. It is incumbent upon those who are present to inform those who are absent because those who are absent might comprehend (what I have said) better than the present audience."

Because Allah, the Exalted, has said: «فاعلم أنه لا إله إلا الله‏» (So know that there is no deity worthy of worship except Allah), thus Allah began with knowledge. And (in the hadith it is mentioned) that the scholars are the heirs of the prophets. (And) the prophets left as inheritance only knowledge. So whoever acquires knowledge has indeed acquired a great share. And whoever treads a path seeking knowledge, Allah makes the path to Paradise easy for him. And Allah, the Exalted, has said that only those of His servants fear Allah who have knowledge. And (in another place) He said: and none comprehend it except the scholars. And He said: and those (disbelievers) said, "If only we had listened or used reason, we would not be among the companions of the Blaze." And He said: Are those who know equal to those who do not know? And the Messenger of Allah (peace and blessings be upon him) said: When Allah intends good for someone, He grants him understanding of the religion. And knowledge is only acquired by learning. And Abu Dharr (may Allah be pleased with him) said: If you were to place the sword here—and he pointed to his neck—and I thought that I could convey even a single word I heard from the Prophet (peace and blessings be upon him) before my neck was struck, I would certainly convey it. And the Prophet (peace and blessings be upon him) said: Let the one who is present convey (my words) to the one who is absent. And Ibn Abbas (may Allah be pleased with them both) said that by the verse «كونوا ربانيين‏» is meant the wise, the jurists, the scholars. And «رباني» refers to the one who educates people in knowledge by explaining minor issues before major ones.

Narrated Ibn Mas`ud: The Prophet used to take care of us in preaching by selecting a suitable time, so that we might not get bored. (He abstained from pestering us with sermons and knowledge all the time).

Narrated Anas bin Malik: The Prophet said, "Facilitate things to people (concerning religious matters), and do not make it hard for them and give them good tidings and do not make them run away (from Islam).

Narrated Abu Wail: `Abdullah used to give a religious talk to the people on every Thursday. Once a man said, "O Aba `Abdur-Rahman! (By Allah) I wish if you could preach us daily." He replied, "The only thing which prevents me from doing so, is that I hate to bore you, and no doubt I take care of you in preaching by selecting a suitable time just as the Prophet used to do with us, for fear of making us bored."

Narrated Muawiya: I heard Allah's Apostle saying, "If Allah wants to do good to a person, He makes him comprehend the religion. I am just a distributor, but the grant is from Allah. (And remember) that this nation (true Muslims) will keep on following Allah's teachings strictly and they will not be harmed by any one going on a different path till Allah's order (Day of Judgment) is established."
