Allah the Exalted teaches His believing servants to avoid the ways of the disbelievers and hypocrites,

﴿ظٹط£ظژظٹظ‘ظڈظ‡ظژط§ ط§ظ„ظ‘ظژط°ظگظٹظ†ظژ ط،ظژط§ظ…ظژظ†ظڈظˆط§ظ’ ط¥ظگط°ظژط§ طھظژظ†ظژط§ط¬ظژظٹظ’طھظڈظ…ظ’ ظپظژظ„ط§ظژ طھظژطھظژظ†ظژظ€ط¬ظژظˆظ’ط§ظ’ ط¨ظگط§ظ„ط¥ظگط«ظ’ظ…ظگ ظˆظژط§ظ„ظ’ط¹ظڈط¯ظ’ظˆظژط§ظ†ظگ ظˆظژظ…ظژط¹ظ’طµظگظٹظژط©ظگ ط§ظ„ط±ظ‘ظژط³ظڈظˆظ„ظگ﴾

(O you who believe! When you hold secret counsel, do it not for sin and wrongdoing, and disobedience to the Messenger,) meaning, do not hold evil secret counsels like the ignorant disbelieving People of the Scriptures and their allies among the hypocrites, who imitate their ways,

﴿ظˆظژطھظژظ†ظژظ€ط¬ظژظˆظ’ط§ظ’ ط¨ظگط§ظ„ظ’ط¨ظگط±ظ‘ظگ ظˆظژط§ظ„طھظ‘ظژظ‚ظ’ظˆظژظ‰ ظˆظژط§طھظ‘ظژظ‚ظڈظˆط§ظ’ ط§ظ„ظ„ظ‘ظژظ‡ظژ ط§ظ„ظ‘ظژط°ظگظ‰ ط¥ظگظ„ظژظٹظ’ظ‡ظگ طھظڈط­ظ’ط´ظژط±ظڈظˆظ†ظژ﴾

(but do it for Al-Birr and Taqwa; and have Taqwa of Allah unto Whom you shall be gathered.) and He will then inform you of all your deeds and statements; He has counted and recorded them and will justly hold you accountable for them. Allah the Exalted said,

﴿ط¥ظگظ†ظ‘ظژظ…ظژط§ ط§ظ„ظ†ظ‘ظژط¬ظ’ظˆظژظ‰ ظ…ظگظ†ظژ ط§ظ„ط´ظ‘ظژظٹظ’ط·ظژظ€ظ†ظگ ظ„ظگظٹظژط­ظ’ط²ظڈظ†ظژ ط§ظ„ظ‘ظژط°ظگظٹظ†ظژ ط،ظژط§ظ…ظژظ†ظڈظˆط§ظ’ ظˆظژظ„ظژظٹظ’ط³ظژ ط¨ظگط¶ظژط¢ط±ظ‘ظگظ‡ظگظ…ظ’ ط´ظژظٹظ’ط¦ط§ظ‹ ط¥ظگظ„ط§ظ‘ظژ ط¨ظگط¥ظگط°ظ’ظ†ظگ ط§ظ„ظ„ظ‘ظژظ‡ظگ ظˆظژط¹ظژظ„ظژظ‰ ط§ظ„ظ„ظ‘ظژظ‡ظگ ظپظژظ„ظ’ظٹظژطھظژظˆظژظƒظ‘ظژظ„ظگ ط§ظ„ظ’ظ…ظڈط¤ظ’ظ…ظگظ†ظڈظˆظ†ظژ ﴾

(An-Najwa are only from the Shaytan, in order that he may cause grief to the believers. But he cannot harm them in the least, except as Allah permits. And in Allah let the believers put their trust.) Allah states that secret talks, where the believers feel anxious, are

﴿ظ…ظگظ†ظژ ط§ظ„ط´ظ‘ظژظٹظ’ط·ظژظ€ظ†ظگ ظ„ظگظٹظژط­ظ’ط²ظڈظ†ظژ ط§ظ„ظ‘ظژط°ظگظٹظ†ظژ ط،ظژط§ظ…ظژظ†ظڈظˆط§ظ’﴾

(only from Shaytan, in order that he may cause grief to the believers.) meaning, that those who hold such counsels do so because of the lures of the devil,

﴿ظ„ظگظٹظژط­ظ’ط²ظڈظ†ظژ ط§ظ„ظ‘ظژط°ظگظٹظ†ظژ ط،ظژط§ظ…ظژظ†ظڈظˆط§ظ’﴾

(in order that he may cause grief to the believers.) The devil seeks to bother the believers, even though his plots will not harm the believers, except if Allah wills it. Those who are the subject of evil Najwa, should seek refuge in Allah and put his trust in Him, for none of it will harm them, Allah willing. The Sunnah also forbids the Najwa so that no Muslim is bothered by it. Imam Ahmad recorded that `Abdullah bin Mas`ud said that the Messenger of Allah said,

آ«ط¥ظگط°ظژط§ ظƒظڈظ†ظ’طھظڈظ…ظ’ ط«ظژظ„ظژط§ط«ظژط©ظ‹ ظپظژظ„ظژط§ ظٹظژطھظژظ†ظژط§ط¬ظژظ‰ ط§ط«ظ’ظ†ظژط§ظ†ظگ ط¯ظڈظˆظ†ظژ طµظژط§ط­ظگط¨ظگظ‡ظگظ…ظژط§طŒ ظپظژط¥ظگظ†ظ‘ظژ ط°ظ„ظگظƒظژ ظٹظڈط­ظ’ط²ظگظ†ظڈظ‡آ»

(If you were three, then two of you should not hold a secret counsel in the presence of the third person, because that would cause him to be worried.) This Hadith is collected in the Two Sahihs using a chain of narration that contained Al-A`mash. `Abdur-Razzaq narrated that `Abdullah bin `Umar said that Allah's Messenger said,

آ«ط¥ظگط°ظژط§ ظƒظڈظ†ظ’طھظڈظ…ظ’ ط«ظژظ„ظژط§ط«ظژط©ظ‹ ظپظژظ„ظژط§ ظٹظژطھظژظ†ظژط§ط¬ظژظ‰ ط§ط«ظ’ظ†ظژط§ظ†ظگ ط¯ظڈظˆظ†ظژ ط§ظ„ط«ظ‘ظژط§ظ„ظگط«ظگ ط¥ظگظ„ظ‘ظژط§ ط¨ظگط¥ظگط°ظ’ظ†ظگظ‡ظگطŒ ظپظژط¥ظگظ†ظ‘ظژ ط°ظ„ظگظƒظژ ظٹظڈط­ظ’ط²ظگظ†ظڈظ‡آ»

(If you were three, then two of you should not hold a secret counsel in the presence of the third person, except with his permission, because that would cause him to be worried.) Muslim collected this Hadith.

(11. O you who believe! When you are told to make room in the assemblies, make room. Allah will give you room. And when you are told to rise up, then rise up. Allah will exalt in degress those of you who believe, and those who have been granted knowledge. And Allah is Well-Acquainted with what you do.)
