`Ali bin Abi Talhah reported that Ibn `Abbas said: "This means) do not say (anything of which you have no knowledge).'' Al-`Awfi said: "Do not accuse anyone of that of which you have no knowledge.'' Muhammad bin Al-Hanafiyyah said: "It means bearing false witness.'' Qatadah said: "Do not say, `I have seen', when you did not see anything, or `I have heard', when you did not hear anything, or `I know', when you do not know, for Allah will ask you about all of that.'' In conclusion, what they said means that Allah forbids speaking without knowledge and only on the basis of suspicion, which is mere imagination and illusions. As Allah says:

﴿اجْتَنِبُواْ كَثِيراً مِّنَ الظَّنِّ إِنَّ بَعْضَ الظَّنِّ إِثْمٌ﴾

(Avoid much suspicion; indeed some suspicions are sins.) ﴿49:12﴾ According to a Hadith:

«إِيَّاكُمْ وَالظَّنَّنَفَإِنَّ الظَّنَّ أَكْذَبُ الْحَدِيث»

(Beware of suspicion, for suspicion is the falsest of speech.) The following Hadith is found in Sunan Abu Dawud:

«بِئْسَ مَطِيَّةُ الرَّجُلِ: زَعَمُوا»

(What an evil habit it is for a man to say, `They claimed...') According to another Hadith:

«إِنَّ أَفْرَى الْفِرَى أَنْ يُرِيَ الرَّجُلُ عَيْنَيْهِ مَا لَمْ تَرَيَا»

(The worst of lies is for a man to claim to have seen something that he has not seen.) In the Sahih it says:

«مَنْ تَحَلَّمَ حُلْمًا كُلِّفَ يَوْمَ الْقِيَامَةِ أَنْ يَعْقِدَ بَيْنَ شَعِيرَتَيْنِ وَلَيْسَ بِفَاعِل»

(Whoever claims to have seen a dream (when he has not seen) will be told on the Day of Resurrection to make a knot between two barley grains, and he will not be able to do it.)

﴿كُلُّ أُولـئِكَ﴾

(each of those ones) means these faculties, hearing, sight and the heart,

﴿كَانَ عَنْهُ مَسْؤُولاً﴾

(will be questioned.) means, the person will be asked about them on the Day of Resurrection, and they will be asked about him and what he did with them.

﴿وَلاَ تَمْشِ فِى الاٌّرْضِ مَرَحًا إِنَّكَ لَن تَخْرِقَ الاٌّرْضَ وَلَن تَبْلُغَ الْجِبَالَ طُولاً - كُلُّ ذَلِكَ كَانَ سَيِّئُهُ عِنْدَ رَبِّكَ مَكْرُوهًا ﴾

(37. And walk not on the earth with conceit and arrogance. Verily, you can neither rend nor penetrate the earth nor can you attain a stature like the mountains in height.) (38. All the bad aspects of these (the above mentioned things) are hateful to your Lord.)
