In verse 86, it was said: وَمَا أَنَا مِنَ الْمُتَكَلِّفِينَ (nor am I from among those who make up things artificially.).
The blameworthiness of artificial behavior
The statement means: 'I am not declaring my prophethood artificially, nor am I falsely pretending to have knowledge and wisdom, rather, I am conveying the commandments of Allah to you as they are. From this we learn that feigned formality and pretension is blameworthy in the light of the Shari'ah. Accordingly, there are some ahadith that condemn it. In the Sahihayn (al-Bukhari and Muslim), it has been reported from Sayyidna ` Abdullah Ibn Masud ؓ :
"0 people, whoever from among you knows something, let him tell people about it. But, that which he does not know, let him simply say: وَاللہ سبحانہ و تعالیٰ اَعلَم (Allah knows best) (because) Allah Ta` a-la has said about his Rasul قُلْ مَا أَسْأَلُكُمْ عَلَيْهِ مِنْ أَجْرٍ وَمَا أَنَا مِنَ الْمُتَكَلِّفِينَ (Say,"I do not demand from you any fee for it, nor am I from among those who make up things artificially."- 38:86)." (Ruh-ul-Ma’ ani)
