Evil Consequences of Concealment and Distorting Facts During Disputes
In The Name of Allaah, The Most Merciful, The Bestower of Mercy
‘Narrated Umm Salamah (radiyallaahu-anhaa): The Messenger of Allaah (sallal-laahu-alayhi-wasallam) said: Indeed, I am only a human being and you people (i.e. disputants) come to me with your disputes. And it may be that one of you can present his case more eloquently than the other and I consider him truthful, and judge in his favour. So if I ever judge and give the right of a brother to his brother, then it is a piece of hell-fire and let him not take it.” [Book of Judgements: Chapter 29: Hadeeth Number: 7181]
Some benefits derived from this hadeeth in Fat-hul Baari
 The Ummah (i.e. the scholars and judges) have been commissioned to judge based on what is apparent, and the mere judgement of a judge cannot prohibit the lawful and allow the unlawful (because it cannot be taken if proven erroneous).  This Hadeeth contains a refutation against those who say that the Messengers possess knowledge of the unseen.  This hadeeth also shows that speech can be seen to be true in the apparent, but it is truly falsehood with regards to what is hidden within it.  Also this hadeeth shows that the one who receives a judgement in his favour is more aware than every other person as to whether he is entitled to it, or whether he is a falsifier. So he takes it if he is entitled to it, or leaves it if he a falsifier; because in reality a judgment cannot change an affair from what it was in origin (i.e. the original truth in the affair before its distortion or concealment).  Also this hadeeth shows the sinfulness of the one who argues based on falsehood until he receives what he wants publicly, whilst he is upon falsehood.  Also in this hadeeth is proof that a scholar can make a mistake and it is a refutation against those who say that every Mujtahid is correct.  Also this hadeeth shows us that the Mujtahid is forgiven (when he makes a mistake). [End of Paraphrase: For Further details, see Kitaab Al-Ahkaam of Imaam Bukhari with Fathul Baari]
Allaah (The Most High) said:
يَا أَيُّهَا الَّذِينَ آمَنُوا اتَّقُوا اللَّهَ وَكُونُوا مَعَ الصَّادِقِينَ
‘’O you who believe! Be afraid of Allah, and be with those who are truthful’’ [9:119]
”Be with those who are truthful” in their statements, actions and state of affairs. Those whose statements are truthful, and their actions and state of affairs are not except truth—free from negligence and laxity, safe from evil goals and gathered upon sincerity (to Allaah) and a sincere intention; for indeed truthfulness leads to righteousness and righteousness leads to paradise. [End of quote: For further details, see: Tayseer Al-kareem Ar-Rahman Fee Tafseer Kalaam Al-Mannaan of Imaam as-Saa’di]
Therefore, let this be a reminder to every quarrelsome person who seeks to make a claim to something he is not entitled to—those who employ deceit and concealment in times of dispute; those who make claims to that which they do not possess and persist in error, whilst enticing the common people towards blameworthy emotions, so that they are defended and shown sympathy.
Let this be a reminder to all those who accuse others of bad manners when their plots and plans are unveiled–Is it good manners that truth is concealed and its upholders are portrayed with a bad image?! Is it good manners that a person deliberately entices the common people towards holding onto ambiguities, whilst uttering false speech against the Salafi students, who truthfully transmit the clear-unambiguous statements of the scholars?! Obviously it is not expected that any honest person will affirm that these are good things. So we must all fear Allaah and remember that He (The All-Knowing) knows everything we intend and do.
And Allaah knows best
