(And of mankind there is he whoso conversation on the life of this world pleaseth thee (Muhammad)) [2:204].
Said al-Suddi: “This was revealed about al-Akhnas ibn Shurayq al-Thaqafi, an ally of Banu Zuhrah. He came to the Prophet, Allah bless him and give him peace, in Medina, and pretended to be a Muslim. The Prophet, Allah bless him and give him peace, admired him for this. He said: ‘I have come to embrace Islam, and Allah knows I am truthful’, this is what Allah states when He says (and he calleth Allah to witness as to that which is in his heart). Upon leaving the Messenger of Allah, he passed by a cultivated field and some asses which belonged to some Muslims. He burned the field and hamstrung the asses. Allah, exalted is He, revealed about him (And when he turneth away (from thee) his effort in the land is to make mischief therein and to destroy the crops and the cattle) [2:205]”.
