In The Name of Allaah, The Most Merciful, The Bestower of Mercy
Imaam Muhammad ibn Saaleh Al-Uthaymeen [rahimahullaah] said: Indeed, our Shaikh -The Diligent One- Abdur Rahmaan As’Sadi [rahimahullaah] related to me that it has been stated about Al-Kisaa’ee -an Imaam of the people of koofa- that he sought after the knowledge of Arabic grammar but could not [grasp it or was unable to progress]. One day, he found an ant carrying its food whilst ascending a wall. Whenever it ascended, it fell off; but it persevered until it overcame this obstacle and ascended the wall. Al-Kisaa’ee said, ‘’This ant persevered until it reached its goal.’’ So, he persevered until he became an Imaam in Arabic grammar. [ref 1]

In The Name of Allaah, The Most Merciful, The Bestower of Mercy
Imaam Muhammad Ibn Saaleh Al-Uthaymeen (rahimahullaah) said that some of the people say that sincere intention in this present era of ours is difficult (to achieve) or it may be impossible (to achieve) because those who seek knowledge do so with the aim of receiving a certificate.
The Shaikh replied to this statement saying that one’s intention is regarded to be corrupt if knowledge is sought in order to receive a certificate or a desire for an elevated worldly status by way of it. But a person’s intention is regarded to be good and not in opposition to sincerity if he wants an elevated status in order to benefit the people, for he knows that at present it is impossible for a person to achieve a high and beneficial position for the Ummah unless he has a certificate. And because of this, even if you were to find a scholar who is good in various affairs of knowledge but he has no certificate, it will not be possible for him to teach even in high school and this is the reality. And you will find that the one lesser in knowledge than this scholar will be accepted (as a teacher) at a university as long as he has a certificate. So in accordance with a person’s (sincere) intention and choices the certificate is not considered harmful and its obtainment enters into the statement of the Messenger (sallal-laahu-alayhi-wasallam):
وما جاءك من هذا المال وأنت غير مشرف ولا سائل فخذه، وما لا فلا تتبعه نفسك
And what comes to you from this wealth without asking for it or having greed for it, take it; and if not given, do not run for it.” [Saheeh Al-Bukhaari. Number 1473. Vol 2. Book of Zakat]
See Sharh Hilya Taalib Al-Ilm’ page:22
Shaikh Saaleh Al-Fawzaan [may Allaah preserve him] says:
“The people of knowledge [i.e. the scholars] are of the view that it is obligated on the Muslims in every era that if they are certain about the presence of this filthy doctrine [i.e. the doctrine of the khawaarij], they should remedy it through calling to Allaah [i.e. the correct way] and enlighten the people about that. If they [i.e. khawaarij] do not obey [and come out fighting], then they are fought [by the Muslim ruler] in order to repel their harm.”

Chapter: The Statement of the Prophet: [Whoever is able to marry, should marry, for that will help him lower his gaze and guard his modesty (i.e. his private parts from committing illegal sexual intercourse etc.).’ And should a person marry (even if) he has no desire for marriage?] [Kitaabun Nikaah’ Saheeh Al-Bukhaari’ Hadeeth Number 5065]
“While I was with Abdullaah, uthman met him at Mina and said, ‘O Abu Abdur-Rahmaan! I have something to say to you.’ So both of them went aside and uthmaan said, ‘O Abu Abdur-Rahmaan! Shall we marry you to a virgin who will make you remember your past days? When Abdullaah felt that he was not in need of that, he beckoned me (to join him) saying, ‘O Alqamah’ Then I heard him saying (in reply to uthmaan), ‘As you have said that, (I tell you that) the Prophet (sallal-laahu-alayhi-wasallam) once said to us, ‘O young people! Whoever among you is able to marry, should marry, and whoever is not able to marry, is recommended to observe fast as fasting will diminish his sexual power’.
Imaam Abdul Azeez Bin Baaz [rahimahullaah] explains:
“Therefore, getting married is the correct [thing to do] as an obligation upon the one who has shahwa [sexual desires] even if he is not in fear of falling to Zinaa, and this is with regards to the one whose situation allows him to get married. This [also shows] Uthman’s righteous moral conduct and that the elderly person can get married as long as he has the strength for sexual relations; and those mainly intended in this hadeeth are the young people, because in most cases they possess greater desires and are more in need of that.”

Abdul Hameed Bin Abdillaah Ibn Muslim Ibn Yasaar [rahimahullaah] said:
“When Ibn Seereen [rahimahullaah] was imprisoned, the prisoners said to him, ‘’Go to your family at night and return in the morning”. So he said: By Allaah! I will not deceive the ruler.””

Among The Virtues of The Prophet’s City- By Imaam Muhammad Ibn Saaleh Al-Uthaymeen (Rahimahullah)
Imaam Muhammad Bin Saaleh al-Uthaymeen (rahimahullaah) was asked about the statement of the Messenger (sallal-laahua-alayhi-wasallam) that: ‘’Verily Imaan returns and goes back to Madeenah as a snake returns and goes back to its hole.’’
In this hadeeth the Messenger (sallal-laahu-alayhi-wasallam) said: ‘’ Verily Imaan returns and goes back to Madeenah as a snake returns and goes back to its hole.’’ The word (يَأرِزُ)-Yarizo with a kasrah on the letter Raa can also have a Fatha or a Dammah (on the Raa). And the meaning of (يَأرِزُ) – Yarizo is that (Islaam) will return and it will be established in Madeenah, just as a snake returns to its hole after exiting it. This is an indication from the Prophet (sallal-laahu-alahi-wasallam) that this religion will return to Madeenah after the other lands become corrupted, just as a snake goes out and roams about in the earth, and then returns to its hole after that.
In this hadeeth is also an indication that just as Islaam did spread from Madeenah, it will also return to it; for indeed Islaam’s strength and authority did not spread except from Madeenah, even though its origin was in Makkah. Makkah was the first place where the revelation came down, but the Muslims were not able to establish a state, authority and Jihaad except after migrating to Madeenah. So for this reason, Islaam’s authority, enforcement and strength spread from Madeenah, and it will return to it in the end of time.
And some of the people of knowledge say that this (hadeeth) is indicative of an affair that has preceded, and that people did come to Madeenah and return to it in order to acquire the knowledge of the Sharee-ah and to study Islaam. However, the first meaning is what is apparent from the hadeeth.
