AL-BAQARA (THE COW) : 75-82

2:75. Can ye (o ye men of Faith) entertain the hope that they will believe in you?- Seeing that a party of them heard the Word of Allah, and perverted it knowingly after they understood it.
2:76. Behold! when they meet the men of Faith, they say: "We believe": But when they meet each other in private, they say: "Shall you tell them what Allah hath revealed to you, that they may engage you in argument about it before your Lord?"- Do ye not understand (their aim)?

2:77. Know they not that Allah knoweth what they conceal and what they reveal?
2:78. And there are among them illiterates, who know not the Book, but (see therein their own) desires, and they do nothing but conjecture.
2:79. Then woe to those who write the Book with their own hands, and then say:"This is from Allah," to traffic with it for miserable price!- Woe to them for what their hands do write, and for the gain they make thereby.

2:80. And they say: "The Fire shall not touch us but for a few numbered days:" Say: "Have ye taken a promise from Allah, for He never breaks Hiromise? or is it that ye say of Allah what ye do not know?"
2:81. Nay, those who seek gain in evil, and are girt round by their sins,- they are companions of the Fire: Therein shall they abide (For ever).

2:82. But those who have faith and work righteousness, they are companions of the Garden: Therein shall they abide (For ever).
