Shaykhul-lslaam Ibn Taymiyyah (d.728H) – rahimahullaah – said:
The position of wealth should be regarded like that of the toilet, in that there is need for it, but it has no place in the heart, and it is resorted to when needed.
 Wasiyyatus-Sughraa (p.55) of Ibn Taymiyy ah.

Al-Bayhaqee relates from Ibn ‘Umar radiallaahu ‘anhu that AlIaah’s Messenger sallallaahu ‘alayhi wa sallam said:
“For everything there is a polish, and the polish for the hearts is the dhikr (remembrance) of Allaah.
There is nothing more potent in saving a person from the punishment of Allaah than the dhikr of Allaah.” It was said: Not even Jihaad in the path of Allaah. So he replied: “Not even if you were to continue striking with your sword until it breaks.” 
 Saheeh: Related by Ahmad (4/352), from Mu’aadh ibn Jabal radiallaahu ‘anhu. It was authenticated by al-Albaanee in Saheehul-Jaami’ (no.5644)

Imaam Ibn Seereen (rahimahullaah) said :
‘Indeed, This knowledge Is Deen,
So Look To The One You Take Your Deen From
‘Umar ibn Abdil-’Aziz said:
Become a scholar if you are able.
If you are not able, then be a student.
If you can not, then show love for them.
If you are unable to do that, then (at least) do not hate them.

Ibraaheem ibn Faatik said: I heard Aboo Ya`qoob say:
This world is an ocean, and the Hereafter is that distant shore, the boat to be traveled within is fear of Allaah, and the people are travelers within it.

Abu Al-Hasan Ali bin Ahmad said:
“Deal with optional acts of worship as if they are obligatory, and acts of disobedience as if they are kufr (disbelief), and your desires as if they are poison, and socializing with the people as if it were fire, and nurturing of your soul as if it were medicine.”
Khilasat Al-Athaar, 3/401
Ibrâhîm ibn Adham (d.160H) – rahimahullâh – said, when he was asked about the verse: “Call upon Me and I will respond to you.” [Sûrah Ghâfir 40:60] They said: We call upon Allâh, but He does not respond to us. So he said:
“You know Allâh; yet you do not obey Him.
You recite the Qur’ân; yet you do not act according to it.
You know Shaytân; yet you continue agreeing with him.
You claim to love Allâh’s Messenger ‘alayhis-salâm; yet you abandon his Sunnah (guidance and way).
You claim to love Paradise, yet you do not work for it.
You claim to fear the Fire; yet you do not stop sinning.
You say, Indeed death is true; yet you have not prepared for it.
You busy yourselves with the faults of others; yet you do not look at your own faults.
You eat the sustenance that Allâh provides for you; yet you are not grateful to Him.
And you bury your dead; yet you have not heeded its lesson.” 
 Al-Hâfidh Ibn Rajab related it in al-Khushû’ fis-Salâh (p.62).
