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.

“I fear that Salafiyyûn one day will say: ‘Photography isn’t ‘picture making’. You just press a button.’.”
(Silsilat-ul-Hudâ wan-Nûr 393)
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).
From Living to Die or Dying to Live!
“Speech by itself is worthless, unless it is followed by action.Speech and action by themselves are worthless, unless they have the right intention. And speech, action, and the right intention are worthless unless they agree with the Sunnah.”
Abdullah ibn Mas’ūd [Jaami’ al-Uloom, p. 70]”
Imaam malik said,
“The sunnah is like Ark of Noah.
Whoever embarks upon it reaches salvation and
whoever refuses is drowned.”
Quoted by Shaikh ul-Islam Ibn Taimiyyah in majmoo’ ul-fataawaa (4/57).
Luqman said to his son:
O dear son! Sit with the scholars. Allâh gives life to hearts with wisdom in the same way as He gives life to the dead land with rain.
(Jami’ Bayan-il-‘ilm 1/211)
