Why our Du'as are not answered?

by ibn Rajab al Hanbali
from Khushu' fis-salah

Ibrahim ibn Adham - may Allah have mercy on him - a third century scholar, a teacher and a companion of Sufyan ath-Thawri, was asked about the saying of Allah - the Most High:

"and your Lord says: "Call on me I will answer your prayer..."
[40:60]

"We supplicate and we are not answered."
So he said to them:

You know Allah, Yet you do not obey Him,

You recite the Qur'an, Yet do not act according to it,

You know Shaitan, Yet you have agreed with him,

You proclaim that you love Muhammad Yet you abandon his Sunnah,

You proclaim your love for Paradise, Yet you do not act to gain it,

You proclaim your fear the Fire, Yet you do not prevent yourselves from sins,

You say "Indeed death is true", Yet you have not prepared for it,

You point out the faults with others, Yet you do not look at your faults,

You eat of that which Allah has provided for you, Yet you do not thank Him,

You bury your dead, Yet you do not take a lesson from it."

ACCUMULATOR EFFECT

Hello again ABDUL AZIZ,

In you last hydraulics email, I explained why
the charge pump in a hydrostatic transmission is
pure heat load and how one hydraulic equipment
user's failure to understand this cost him dearly.

Today, another issue to be aware of with hydrostatic
transmissions and a simple technique to minimize it:

When a hydrostatic transmission is subject to a
sudden increase in load, the motor stalls momentarily
and system pressure increases until the increased load
is overcome or the high pressure relief valve opens -
whichever occurs first.

While the motor is stalled, there is no return flow
from the outlet of the motor to the inlet of the pump.
This means that the transmission pump will cavitate
for as long as it takes to make-up the volume of fluid
required to develop the pressure needed to overcome
the increased load (or the high-pressure relief valve).

How long the pump cavitates depends on the
output of the charge pump, the magnitude of
the pressure increase, and its influence on
the increase in volume of the pipe or hose,
and the decrease in volume of the fluid.

This is called the 'accumulator effect'

One way to minimize stalling and pressure spikes
and the resulting 'accumulator effect'
in applications where the load on the transmission
varies - in say drill rigs for example, is to
install a flywheel between the hydraulic motor
and reduction box.

The stored energy in the flywheel assists the
hydrostatic drive to maintain speed and torque,
and minimize the magnitude of pressure fluctuations
resulting from sudden increases in load.


Yours for better hydraulics knowledge,

SECRET OF AL-IKHLAS

ﻪﺗﺎﮐﺭﺑﻭ ﷲﺍ ﺔﻣﺣﺭﻭ ﻢﻛﻴﻠﻋ ﻢﻼﺳﻟﺍ
Keberkatan surah al-ikhlas

Ketika Memulakan Kerja

Bacalah ayat ini sebelum anda memulakan apa-apa saja kerja kerana dengan bacaan ini akan keluarlah iblis dan syaitan yang berada didalam tubuh kita dan juga di sekeliling kita, mereka akan berlari keluar umpama cacing kepanasan.

Sebelum Masuk Ke Rumah

Sebelum anda masuk rumah, bacalah surah Al-Ikhlas (sebanyak 3 kali. Masuklah rumah dengan kaki kanan dan dengan membaca bismillah.. Berilah salam kepada anggota rumah dan sekiranya tiada orang di rumah berilah salam kerana malaikat rumah akan menyahut.Mereka yg sentiasa membacanya ketika memasuki rumah nescaya akan bertambah lapang rezeki dan keadaannya.
Amalkanlah bersolat kerana salam pertama (ianya wajib) yang diucapkan pada akhir solat akan membantu kita menjawab persoalan kubur. Apabila malaikat memberi salam , seorang yang jarang bersolat akan sukar menjawab salam tersebut. Tetapi bagi mereka yang kerap bersolat, amalan daripada salam yang diucap di akhir solat akan menolongnya menjawab salam malaikat itu.

Ketika Sakit

Sabda Rasulullah S.A.W yang bermaksud: Barangsiapa membaca surah Al-Ikhlas sewaktu sakit sehingga dia meninggal dunia, maka dia tidak akan membusuk di dalam kuburnya, akan selamat dia dari kesempitan kuburnya dan para malaikat akan membawanya dengan sayap mereka melintasi titian siratul mustaqim lalu menuju ke syurga. Demikian diterangkan dalam Tadzikaratul Qurthuby ).

Khatam al-Quran

Rasulullah SAW pernah bsabda. Tidak kuasakah kamu membaca sepertiga Al-Quran pada tiap-tiap malam? Meraka yakni para sahabat r.hum. btanya, bgaimanaka ya Rasulullah s.a.w.? Bacalah Surah Ikhlaas serupa gn spertiga Al-Quran.

Pahala Membacanya

Abu Hurairah r.a mberitakan bahawa Nabi s.a.w. mdengar seorg mbaca surah Ikhlaash lantas baginda s.a.w. bersabda : Telah Wajib, Aku btanya wahai kekasih Tuhan apa yg telah wajib? Baginda s.a.w. mjwb Syurga. Brgsiapa mbaca sbyk 50 kali, nescaya Allah s.w.t. mgampunkan dasanya utk selama 50 tahun.

Ibnu Abbas r.a. mgatakan : Brgsiapa mgerjakan 4 rakaat solat, lalu mbaca sura Ikhlaas sbyk 25 kala ditiap2 rakaat, nescaya Allah s.w.t. mgampunkan dasanya utk selama 100 tahun. 50 tahun dahulunya dan 50 tahun kemuiannya.

Brgsiapa mbaca sekali, nescaya Allah s.w.t. akan mnurunkan kbaikan dan kberkatan utknya. dan brgsiapa 5 kali, nescaya Allah s.w.t. akan mnurunkan kbaikan dan kberkatan utk sekelian isi rumahnya dan brgsiapa mbacanya 3 kali, nescaya Allah s.w.t. akan mnurunkan kbaikan dan kberkatan utk sekelian kaum kluarganya dan tertangga.

Brgsiapa mbacanya 10 kali, nescaya Allah s.w.t membinakan Mahligai dilm Syurga

Nota

Jika sekiranya kawan-kawan ingin mengumpul saham akhirat, sampaikanlah ilmu ini kepada kawan2 yang lain. Sepertimana sabda Rasulullah SAW: 'Sampaikanlah pesananku walaupun satu ayat'. Sesungguhnya apabila matinya seseorang anak Adam itu, hanya 3 perkara yang akan dibawanya bersama: (1) Sedekah/amal jariahnya, (2) Doa anak-anaknya yang soleh dan (3) Ilmu yang bermanfaat yang disampaikannya kepada orang lain.

Relief Valve

The word relief means release from anything. Human being created not just to undergo activities related to fulfill the Maslow's Hierachy of Need but the motive is beyond that. Valve in technical term gives definition to control medium. Thus the importance of relief valve not only in mechanical system but also in human.

Human has to be released from stress so need relief valve to control stress. Human has to be released from pain thus relief valve for relieving pain is essential. What are other systems do not require relief valve. Most of the systems biological, chemical, mechanical of course, physical, electrical etc really require relief valves to be incorporated to ensure the function for each individual system smoothly done.

Therefore there must be a need to have relief valve to release anger, to eliminate bad attitude and to extinguish evil from the heart to enable human to carry out the activities in this world to meet the objective of the hereafter.
