In the Name of Allah, the Extremely Merciful, the Bestower of Mercy
Shaykh Saalih al-Fawzaan, may Allah preserve him, said:
Beneficial knowledge is not ample speech or treatises. No, rather [beneficial] knowledge depends on the usool upon which it is built, even if it may be little.

In the Name of Allaah, the Extremely Merciful, the Bestower of Mercy…
Knowledge is not attained except by memorization. Knowledge without memorization does not last.

He the Most High said:
But rather be rabbaaniyyoon (wise scholars who cultivate the people) by teaching them the Book and by studying it. [3:79]
Shaykh Saalih al-Fawzaan (hafidahullaah) comments:
The ‘Rabbaaniyyoon‘ are those who begin with the small matters of knowledge before the greater ones. They cultivate themselves and their students, beginning with the smaller matters and moving on to the larger matters. This is something natural because all things begin from their roots and their foundations and then, they grow bigger and larger after that.(1)
As for the person who pounces upon knowledge from the top, then this person will just tire himself out and will not attain anything. Whereas the one who begins with usool (fundamentals) and proceeds in stages, then this is the person, who, by the Permission of Allaah, will be proceeding in the correct way and with sound direction.
He the Most High said:
They ask you [O Muhammad ﷺ about the ahilah (the crescent moons), say: 'They are signs to mark periods of time for mankind, and for the Hajj. And righteousness is not that you enter the houses from their backs, but rather righteousness is the quality of the person who has taqwa (who fears and is dutiful to Allaah). And enter houses through their proper doors.' [2:189]
Those people asked a question about the crescent moons: “Why does the crescent moon begin as something small and then grow larger until it becomes full, then it gets smaller until it is again a crescent?” So Allaah rebukes them, and directed them towards asking about that which will benefit them, and that they should come to the houses of knowledge from their (correct) doors.(2)
As for asking about the crescent moon, its conditions, its smallness and its largeness, then this has no benefit in it for them.(3) Rather, benefit is that they ask about what they are in need of, and that is awareness of the benefits of the crescent, therefore He said:
Say: they are signs to mark periods of time for mankind [2:189]
So he explained their benefits; and it is that Allaah makes them signs marking periods of time for mankind by means of which they can become aware of acts of worship, dealings and time-spans and other than that.
So he directed them to the benefits of the crescent moons, and he did not respond to their question about the reality of the crescent moons. This is because there was no benefit for them in that, and so that he should direct them towards what is benefiting for them to ask about, and it is the doors to knowledge and not the back-doors of knowledge and the superfluous unnecessary matters they have no need of. And if they do have some need of them, then it is only a slight need.(4)
(1) This is the approach of the scholars with themselves and with others – they begin with smaller books and smaller fundamental matters of knowledge and then build from there. Likewise, this is what we see in natural affairs as well. To reach growth, something begins on its roots and grows larger and larger and stronger from that initial beginning.
(2) The scholars bring this aayah as a proof in this matter about the approach that should be given to knowledge. It is not restricted to what is apparent from the aayah – it also refers to knowledge. The Shaykh said: “They should come to houses of knowledge (meaning the places where knowledge is to be found) from its correct doors.”
(3) Meaning: there is no benefit in asking why the crescent begins in this or that manner. Rather, it will only benefit one to be aware of the benefits/knowledge that lie in the crescent moons.

In the Name of Allaah, the Extremely Merciful, the Bestower of Mercy. . .
Yusuf ibn ul-Hussayn said I heard Danoon Al-Misree say:
- Whoever cleanses his heart (with ikhlaas) Allaah will beautify his outer appearance;
- Whoever amends that which is between him and Allaah; Allaah will amend for him that which is between him and the people;
- And whoever amends his affairs of the Hereafter, Allaah will amend his worldly affairs.(1)
