‘Umar bin Al-Khattab (may Allah be pleased with him) said:

One day we were sitting in the company of Allah’s Massenger (peace be upon him), when there appeared before us a man dressed in extremely white clothing; his hair was extraordinarily black. There were no signs of travel on him and none of us knew him. He (proceeded until) he sat before the Massenger (peace be upon him), his knees supported against the Prophet’s, his palms placed on his thighs, and said, “O Muhammad, tell me about Islam.” The Messenger of Allah (peace be upon him) said, “Islam is to testily that there is no god but Allah, and that Muhammad is the Messenger of Allah; and that you establish prayer, pay zakah (obligatory charity), observe the fast of Ramadan, and perform pilgrimage to (Allah’s) House if you have the means to do so.” (The inquirer) said, “You have told the truth.” ‘Umar bin AI-Khattb commented, “It astonished us that he would ask and then verify the truth.” (The inquirer) said, “Inform me about iman (faith).” Allah’s Messenger replied, “It is that you believe in Allah, His angels, His Books, His Massengers, the Day of Judgment, and that you believe in Divine Preordination, whether good or bad.” (The inquirer) responded, “You have told the truth.” He then said, “Inform me about ihsan (beneficence).” Allah’s Messenger said, “(It is) that you worship Allah as if you see Him, for though you don't see Him, (you know) He sees you.” The inquirer said, “Inform me about the hour (of the Day of Judgment).” The Messenger of Allah remarked, “The one being asked knows no more than the questioner.” The inquirer said, “Tell me some of its signs.” He (the Holy Prophet) said, “(They are) that the slave-girl will give birth to her mistress (or master), and that you will find barefooted, destitute goat-herders vying with one another in the construction of magnificent buildings.” The narrator, (‘Umar bin Al-Khattab] said, “Then he [the inquirer] went on his way but I stayed with him [Allah’s Messenger] for a long while.” He then said to me, “’Umar, do you know who this inquirer was?’ I replied, ‘Allah and His Messenger know best.’ He remarked, ‘It was (the angel) Gabriel. He came to you [people] in order to teach you your religion.’”

“The Holy Prophet (peace be upon him) delivered an eloquent sermon, which greatly moved us and sent a wave of fear into our hearts and our eyes shed tears.

Those of you who survive me will notice many differences. It will be incumbent upon you to follow my Sunnah (tradition) and the practices of my rightly guided successors (Caliphs) and hold fast with these precepts and traditions and beware of innovations and inventions in religion, because every innovation leads to the wrong path.’ ”

Hadith 8 :

It was narrated on the authority of Abu ‘Abdullah An-Nu‘uman bin Bashir (may Allah be pleased with them) who said, “I heard the Messenger of Allah (peace be upon him) saying,

“That which is lawful is clear, and that which is unlawful is clear and between the two of them are doubtful [or ambiguous] matters about which not many people are knowledgeable. Thus, he who avoids these doubtful matters certainly clears himself in regard to his religion and his honor. But he who falls into the doubtful matters falls into that which is unlawful, like the shepherd who pastures around a sanctuary, all but grazing therein. Verily, every king has a sanctuary, and Allah's sanctuary is His prohibitions. In the body there is a piece of flesh which, if it is sound, all of the body is sound, and which, if it is diseased, all of the body is diseased. This part of the body is the heart.’ ”
