Ibn
Umar, may Allah be pleased with him, relates that the Holy
Prophet, peace and blessings of Allah be upon him, said:
"Islam is based on five articles:
1. To bear witness that there
is none worthy of worship save Allah and that Muhammad (peace
and blessings of Allah be upon him) is the Messenger of
Allah.
2. To observe Prayer (Salat).
3. To Pay Zakat (Alms giving)
4. To perform the Pilgrimage to the House of Allah
(Hajj).
5. To Observe fasting during Ramadhan." (Bukhari)
Abdullah ibn Amr bin Aas, may Allah be pleased with them,
relates that the Holy Prophet, peace and blessings of Allah
be upon him, said:
"A Muslim is one against whose tongue and hands other Muslims
are secure, and an Emigrant is one who departs from what
Allah has forbidden." (Bukhari)
