Learning Assembly in Linux

For someone who struggled in the security world Assembly language is a compulsory language to master. Because this language is the language of low-level, close to machine language (binary), then learn the language will be very beneficial. By learning assembly language, more or less automatically we will understand how computers work more deeply.
This article also as the opening before I discuss the shellcode, buffer overflow and other exploitation techniques that require an understanding of the assembly and operating systems. If you want to be a good hacker, you must master the language.
Machine language, Assembly and C
Basically the computer is a digital creatures who only understands digit digits 1 and 0 (binary). The computer would only accept data in binary form and can only understand commands in binary form. Command in binary form is called the machine language.
In general, the program can be viewed as a sequence of steps / command / instructions to accomplish something. Programmer can simply create a program by writing the command in the form of 1 and 0 (machine language), or using a high-level language that is more humane as C, Visual Basic or Java.

The virtue of Sciences Syar'i and studied

By Al-Ustadz Yazid bin Abdul Qadir Jawas
Allaah has praised the science and the owner and encourage worshipers to his knowledge and equip themselves with it. Similarly, the Sunnah of the Prophet sallallaahu 'alaihi wa sallam is sacred.
Imam Ibn Qayyim al-Jawziyyah (d. th. 751 H) rahimahullaah mention more than a hundred virtue syar'i science. In this book the author mentioned only a small part of it. Among them:
[12]. Jihad is demanding science of God and In the Way People Who Demand Sciences Laksana Mujahid Allaah On Road
Prophet sallallaahu 'alaihi wa sallam has said,

    "Whoever we are entering the mosque (masjid Nabawi) in order to learn or teach goodness, then he is like those who strive in the way of Allah, the Exalted. And anyone who entered it for the purpose other than that, then he is like someone who was seeing something that was not hers. "[1]
Al-Imam Ibn al-Qayyim said rahimahullaah, Jihad against the passions has four levels:
First: strive to study the instructions (useful knowledge) and the true religion (good deeds). A person will not achieve success and happiness in the world and the Hereafter except him.
Second: strive to practice science as know.
Third: strive for mendakwahkan science and teach it to people who do not know.
Fourth: strive to be patient in preaching to Allaah and patient with human disturbance. He bore the difficulties of the mission only because of God.

ESSENCE AND KEDUDUDKAN TAUHID

Oleh Al Ustadz Al Fadhil Abu ‘Isa Abdullah bin Salam hafizhahullah

(Ma'had Faculty Ihya 'as Sunnah, Tasikmalaya, West Java)

Tawhid is a phrase familiar to the Muslims. In general, we as Muslims would want or even have been admitted as a person of Tawheed. However, in reality may be still many among us who do not understand the nature and status of this tawhid. Even people who feel they have Tawheed though, may not know the ins and outs of unity clearly. Since the number of Muslims in understanding the nature of schools of monotheism and forget the very great position, then this problem becomes very important to be explained with a clear explanation. We already know that monotheism is one of the religion. Therefore, the explanation should not be separated from the source of religious knowledge, namely the Qur'an and Sunnah refers to the explanation by the expert, namely the clergy.
Understanding Tawheed
The scholars defines monotheism as follows, "Tawheed is the belief of the oneness of God in His rububiyyah, mengikhlaskan worship to Him (in His uluhiyyah, ed.), And menetapkkan the names and attributes of His perfection". Thus, it can be concluded that Tawheed is divided into 3 types, namely monotheism rububiyyah, uluhiyyah monotheism, and monotheism asthma 'wa shifat. This conclusion was taken by the scholars as they examine the arguments of the Qur'an and Sunnah relating to the unity of Allah, the Exalted. For clarity, each of unity will be described in the following discussion. (See 'Aqidatu At-Tauhid, pp. 15-16.)

DAKWAH SALAFIYYAH Oleh Ustadz Arif Fathul Ulum bin Ahmad Saifullah

Dalam pembahasan yang lalu telah kami jelaskan bahwa Salafiyyah bukan suatu hizb (kelompok) atau golongan. Sesungguhnya dia adalah jama'ah yang berjalan di atas jalan Rasulullah Shallallahu 'alaihi wa sallam dan para sahabatnya. Dia bukanlah salah satu kelompok dari kelompok-kelompok yang muncul sekarang ini, karena dia adalah jama'ah yang terdahulu dari zaman Rasulullah Shallallahu 'alaihi wa sallam dan berlanjut terus-menerus di atas kebenaran dan nampak hingga hari kiamat sebagaimana diberitakan oleh Rasulullah Shallallahu 'alaihi wa sallam. Maka dakwah Salafiyyah adalah dakwah kepada Islam yang murni bukan dakwah hizbiyyah. Imam dakwah Salafiyyah adalah Rasulullah Shallallahu 'alaihi wa sallam dan para imam yang datang berikutnya dari para sahabat, tabi'in, dan orang- orang yang mengikuti mereka dalam kebaikan hingga hari kiamat. Di antara daulah yang ditegakkan atas landasan dakwah Salafiyyah adalah daulah Su'udiyyah di jazirah Arabiyyah, yang dikenal sebagai pembela dakwah Salafiyyah yang gigih sejak berdirinya hingga saat ini.

ISLAM PEMBELA ORANG-ORANG LEMAH

Tafsir Surah Al-Kautsar

Ini surat Makkiyah, terdiri dari tiga ayat, diturunkan setelah surat Al-‘Adiyat. Hubungan surat ini dengan surat sebelumnya (surat Al-Ma‘un), adalah bila Allah menjelaskan dalam surat terdahulu tentang orang yang mendustakan agama dengan empat macam sifat, yaitu al-bukhl (bakhil), tidak mau melakukan salat, riya, dan tidak mau memberikan pertolongan, maka dalam surat Al-Kautsar Allah menyebutkan sifat-sifat yang dikaruniakan kepada Rasulullah Saw. berupa kebaikan dan keberkahan. Disebut-kan bahwa beliau diberi Al-Kautsar, yang berarti kebaikan yang banyak, dorongan untuk melakukan salat dan membiasakan-nya, ikhlas dalam melakukannya dan bersedekah kepada kaum fuqara.

Shodaqoh dan Kesyukuran

Dan (ingatlah juga), tatkala Tuhanmu mema`lumkan: “Sesungguhnya jika kamu bersyukur, pasti Kami akan menambah (ni`mat) kepadamu, dan jika kamu mengingkari (ni`mat-Ku), maka sesungguhnya azab-Ku sangat pedih”. (qs. Ibrahim: 7)
Seseorang yang bershodaqoh tentu merasa bahwa Allah telah memberi dirinya rizqi yang banyak, cukup untuk dirinya, keluarga dan dapat dibagi untuk orang lain yang membutuhkan. Seakan dia berkata, “Terimakasih wahai Allah! Sungguh Engkau telah memberi aku rizqi yang banyak hingga aku bisa bershodaqoh.”
Adapun orang yang bakhil tentu merasa bahwa rizqi yang Allah beri adalah terlalu sedikit untuk dibagi. Ini adalah bukti atas pengingkarannya (kekufurannya) terhadap rizqi dan ni’mat yang Allah beri. Seakan dia berkata, “Ya Allah! Rizqi dariMu ini sangat sedikit untuk dibagi dengan orang lain.”
Maka orang yang bershadaqoh itu adalah orang yang bersyukur dan akan mendapatkan tambahan ni’mat dari Allah di dunia dan akhirat. Adapun orang yang bakhil lagi kufur, maka Allah mengancamnya dengan siksaan.
Adapun orang yang memberikan (hartanya di jalan Allah) dan bertakwa, dan membenarkan adanya pahala yang terbaik, maka Kami kelak akan menyiapkan baginya jalan yang mudah. (Al-Lail: 5-7)
Sebaliknya, jika kita bakhil, maka Allah akan menyiapkan bagi kita jalan yang sukar. Sukar di sini tidak selalu sukar penghidupan. Bisa saja ekonominya mapan, tetapi kita mudah sekali berbuat ma’siat dengan fasilitas yang disediakan itu. Sedangkan ma’siat itu akan menjadi jalan yang sukar bagi kita di akhirat. Bahkan sukarnya akibat ma’siat itu dapat dirasakan juga di dunia dengan adanya berbagai mushibah seperti anak yang durhaka, sakit yang berat, dlsb.
Adapun mereka yang senang bersyukur dengan cara bershodaqoh, maka bagi mereka ada kemudahan kepada jalan yang mudah. Mudah di dunia dan juga di akhirat. Mudah beribadah, punya lingkungan yang baik, keluarga yang baik, dijaga dari mushibah, dlsb.
