Najwa, Gharrar, and Laghwa are forbidden. (mentioned again)

This is so important that it is worth mentioning again and again. Many people use Gharrar, Najwa and Laghwa in name games. You will look at something kinda like what Bart Simpson used to do when he would call that particular bar on the Simpsons. They are called the Bart Simpson prank calls. This is something that is actually forbidden to do to the Nabi (infinite saws) and if it is not to be done to the Prophet (infinite saws) then, one can guess that it is not lawful to do to his (saws) followers. Some individuals do this with names and words for the purpose of some verbal contractual agreement that the person doesn't know that they are involved in. This type of thing is called Najwa, and Gharrar. And being ambiguous about the words or names is called Laghwa which also connotes obscenity. The Messiah (infinite saws) spoke well when he said:

8 For everyone who asks, receives. Everyone who seeks, finds. And the door is opened to everyone who knocks. 9 You parents -- if your children ask for a loaf of bread, do you give them a stone instead? 10 Or if they ask for a fish, do you give them a snake? Of course not! 11 If you sinful people know how to give good gifts to your children, how much more will your Heavenly Lord give good gifts to those who ask him. 12 "Do for others what you would like them to do for you. This is a summary of all that is taught in the law and the prophets. Here is the video:

The believer is one that does not engage in gharrar (buying & selling when person doesn't know wht they've bought or sold); najwa (involving the Nabi or muslim in a plan they know nothing about. Also, called "secret counsels". Sometimes bad even if plan is for good); & laghwa (using ambiguous speech) Allah has said that there is no Laghwa in Paradise. I believe that doing these 3 things will cause the doer to lose Paradise (Jannah, The Gardens).
‎"They shall there exchange, one with another, a (loving) cup free of frivolity (laghwa), free of all taint of ill."~Holy Quran 52:23
{Laghwa means vain talk or obscene language, but, also connotes ambiguity.}

‎"Turnest thou not thy sight towards those who were forbidden secret counsels (najwa) yet revert to that which they were forbidden (to do)? And they hold secret counsels among themselves for iniquity and hostility, and disobedience to the Apostle. And when they come to thee, they salute thee, not as God salutes thee, (but in crooked ways): And they say to themselves, "Why does not God punish us for our words?" Enough for them is Hell: In it will they burn, and evil is that destination!
O ye who believe! When ye hold secret counsel (najwa), do it not for iniquity and hostility, and disobedience to the Prophet; but do it for righteousness and self- restraint; and fear God, to Whom ye shall be brought back.
Secret counsels (najwa) are only (inspired) by the Evil One, in order that he may cause grief to the Believers; but he cannot harm them in the least, except as God permits; and on God let the Believers put their trust."~Holy Quran 58:8-10

‎"Muslim relates from Abu Hurairah that, "The Messenger(saws) of Allah (swt) prohibited sales of whatever a pebble thrown by the seller hits and sales in which there is a chance of risk (gharrar)"
(Nasir al-Mutarriza:) Gharrar is chance or risk meaning it is not known whether it will come to be or not, such as selling fish in the water or birds on the wing. It includes transactions of unknown things, the particulars of which are not fully comprehended by the buyer and seller (al Mughrib fi tartib al-Mur'rib (y94), 2.100).

Gharrar is also mentioned at Holy Quran 7:22, "So by deceit (bi ghuruwr) he brought about their fall: when they tasted of the tree, their shameful parts became manifest to them, and they began to sew together the leaves of the Garden over their bodies. And their Lord called unto them: "Did I not forbid you that tree, and tell you that Satan (Aoudhubillahi) was an avowed enemy unto you?"

It is probably safe to say that the only ones that are free to practice Najwa would be Allah (swt) Himself and His Malaika (Angels).
