Islam is the largest religion and is growing day by day (Alhamdulillah). Rasulullah (Sallallaho Alaihe Wasallam), said: "Islam is to testify that there is no God but Alá and Muhammad is the Messenger of Allah, to perform the prayers, pay the Zakaat to fast in Ramadan and make the pilgrimage to the House if you are able to do so".
Imaan (belief), Salah (prayer), fast, Zakaat and pilgrimage to the House (of Allah Ta' wing) also referred to as the five pillars of Islam. These are the compulsory duties of a Muslim to carry out these activities.
Islam is basically divided into three main categories. Everything goes when Hazrat Ibrahim (A.S) and his son Hazrat Ismail (A.S) were building the House of Allah and were praying. Koran speaks of his prayer: "our Lord!" Send including an own Messenger who shall rehearse Thy signs instruct them in Scripture and wisdom and sanctify them: because you are the sorrow of might, the wise. "
Hazrat Ibrahim prayed to Allah (SWT) to send a Messenger to this man that does three things:
call them to Allah (SWT), preaching
instruct in Scripture and wisdom
the last is to sanctify them
In fact this payer was for Rasulullah (Sallallaho Alaihe Wasallam). Allah Ta' wing kept his promise and sent to his beloved messenger Hazrat Muhammad (SAW) for the guidance and direction of this man.
Rasulullah (Sallallaho Alaihe Wasallam) used to do all these things; I used to call people to Allaah Ta' wing. He was who broke the distance, race and color barriers saying "La Ilaha ill Alá Muhammadur Rasool Allah (God does not exist only Alá, Muhammad is the Rasool (Messenger) of Allah)". Sun, Earth of the Moon, stars, trees, all they are the signs of Allah (SWT). Rasulullah (Sallallaho Alaihe Wasallam) used to recite the Koran Ayats and convince people about the oneness of Allah, that this was the first work of Hazrat Muhammad (SAW).
The second Department of Islam is learning the wisdom of Islam through writing. There were 72 people called Ashab-e-Suffa. Used to learn the Koran and the Hadith of Rasulullah (Sallallaho Alaihe Wasallam) in Masjid-e-Nabwi.
The third and final Department of Islam is to purify the souls. Rasulullah (Sallallaho Alaihe Wasallam) used to purify the souls of the Sahaba (R.A). After the departure of Hazrat Muhammad (SAW) of this world, the sahabs keeps working in these three departments but then there was a serious weakness in all departments.
Many Muslims placed in the race of energy crisis which is against the teachings of the Koran. When Muslims began to Jihad for money, they began to learn the Koran of wealth and there was khankas (Khankah is a place where scholars of Islam purify the souls of his followers) only to "generate business", began the fall of Muslims.
(All praise is due to Allah, Lord of the kingdoms; and prayers and peace of Allah be our Prophet Muhammad and all his family and companions).
