问题15：从细节上看，有什么证据表明伊斯兰教被定义为这一宗教的五根支柱？
Q 15: What is the proof that Islam is defined as being the five pillars of this religion when considered in detail?
A--- 先知（愿主赐其平安）在回答哲布勒伊勒（Gabriel）询问宗教（伊斯兰教）时所说的话："ﷺ
A--- The Prophet's saying (Peace be upon him) upon answering Gabriel when he asked about religion (Islam): "
"伊斯兰教的内涵是：你作见证，除真主外别无应受崇拜者，穆罕默德是真主的使者ﷺ，你谨守拜功，缴纳天课，斋戒莱麦丹月，并且在有能力的情况下朝觐天房（麦加的克尔白）。"（布哈里和穆斯林圣训实录）
"Al-Islam implies that you testify that there is no god but Allah and that Muhammad is the Messenger of Allah, and you establish prayer, pay Zakah, observe the fast of Ramadan, and perform pilgrimage to the House (the Ka' bah in Mecca), if one has the means to do so". (Bukhari and Muslim)
他的圣言"愿主赐他平安"如下：
His saying (Peace be upon him) that reads:
"伊斯兰教的大厦建立在五根支柱之上：崇拜真主独一、履行拜功、缴纳天课、斋戒斋月，以及朝觐（麦加）天房。"
"(The superstructure of) Islam is raised on five (pillars): The Oneness of Allah, performance of Prayer, payment of Zakah, fast of Ramadan, and Pilgrimage (to Mecca)".
（布哈里和穆斯林）
(Bukhari and Muslim)
