Fathwa, - Reconciling between twodefinitions of Islam

Question
assalamu alaykum My Question: On the one hand we have the definition
of islam from shaykh muhammad ibn abdilwahhab)Rahimahullaah( in usul
al thalatha: ,,Islam is submission to Allah through Tawhid, obedience
to His command, and disavowalof Shirk and its people." And on the
other hand, the prophet sall-llaahu alaihi wa sallam said in the
hadith of jibreel:,,Islam is that you witness that there is no god but
Allah and that Muhammad is the Messenger of Allah, and you establish
the prayer, and you give the Zakat, and you fast Ramadan, and you
perform the hajj of the House if you are able to take a way to it."
how is that to understand? please give me a detailed answer. Shukran!
Answer
All perfect praise be to Allaah, The Lord of the Worlds. I testify
that there is none worthy of worship except Allaah, and that Muhammad,
is His Slave and Messenger.
We can reconcile between the two mattersby saying that the definition
ofShaykh Muhammad ibn 'Abdul Wahhaabin his book Al-Usool
Ath-Thalaathah)Three Fundamental Principles( is about Islam in general
which is the comprehensive religion of Islam, Eemaan )faith(, and
Ihsaan )perfection and excellence of worship( while the Hadeeth is
about Islam in its particular meaning. Therefore, he said after the
stated definition: "There are three degrees of Islam, which are:
Islam,Eemaan and Ihsaan. Each of them has its certain pillars."
Nevertheless, the definition ofShaykh Muhammad ibn 'Abdul Wahhaabis
derived from what was mentioned in the stated Hadeeth and that
ofJibreel)Gabriel(. That is because whoever bears witness that there
is none worthyof worship besides Allaahhas disassociated himself from
Shirk )polytheism(, submitted himself to Tawheed )monotheism(, and
whoever fulfills the remaining pillars such as prayer and the like has
submitted himself to obedience.
It was stated in Sharh At-Tahaawiyyah byIbn Jibreen: "The meaning of
Islam according to Sharee'ah terminology is very close to its
linguistic meaning.Shaykh Muhammad ibn 'Abdul Wahhaab,defined it at
the beginning of Al-Usool saying:"Islam is to submit to Allaah by
affirming that He is One, and to surrender to Him by obeying Him and
disavowing Shirk and its people.That is the meaning of Islam which is
very close to its linguistic meaning whichis submission and surrender.
As for its meaning according to Sharee'ah terminology, nothing is
clearer than the definition which the Prophet, gave by naming these
five pillars because they are the bestproof for one's submission,
surrender and commitment, for whoever adheres firmly to those pillars,
he will surrender to his Lord andwill not disobey Him and he will do
them with clear submissiveness as if he is led by reins."Allaah Knows
best.
