Tafsir Ibn Kathir -> Surah Al-Anfal -> Shaytan makes Evil seem fair and deceives the Idolators

Allah said next,

﴿وَإِذْ زَيَّنَ لَهُمُ الشَّيْطَـنُ أَعْمَـلَهُمْ وَقَالَ لاَ غَالِبَ لَكُمُ الْيَوْمَ مِنَ النَّاسِ وَإِنِّي جَارٌ لَّكُمْ﴾

(And (remember) when Shaytan made their (evil) deeds seem fair to them and said, "No one of mankind can overcome you today and verily, I am your neighbor.'')

Shaytan, may Allah curse him, made the idolators' purpose for marching seem fair to them. He made them think that no other people could defeat them that day. He also ruled out the possibility that their enemies, the tribe of Bani Bakr, would attack Makkah, saying, "I am your neighbor.'' Shaytan appeared to them in the shape of Suraqah bin Malik bin Ju`shum, the chief of Bani Mudlij, so that, as Allah described them,

﴿يَعِدُهُمْ وَيُمَنِّيهِمْ وَمَا يَعِدُهُمْ الشَّيْطَـنُ إِلاَّ غُرُوراً ﴾

(He ﴿Shaytan﴾ makes promises to them, and arouses in them false desires; and Shaytan's promises are nothing but deceptions)﴿4:120﴾.

Ibn Jurayj said that Ibn `Abbas commented on this Ayah, (8:48) "On the day of Badr, Shaytan, as well as, his flag holder and soldiers, accompanied the idolators. He whispered to the hearts of the idolators, `None can defeat you today! I am your neighbor.' When they met the Muslims and Shaytan witnessed the angels coming to their aid,

﴿نَكَصَ عَلَى عَقِبَيْهِ﴾

(he ran away), he went away in flight while proclaiming,

﴿إِنِّي أَرَى مَا لاَ تَرَوْنَ﴾

(Verily, I see what you see not.)''

`Ali bin Abi Talhah said, that Ibn `Abbas said about this Ayah,

﴿لاَ غَالِبَ لَكُمُ الْيَوْمَ مِنَ النَّاسِ وَإِنِّي جَارٌ لَّكُمْ﴾

("No one of mankind can overcome you today and verily, I am your neighbor')

"Shaytan, as well as, his devil army and flag holders, came on the day of Badr in the shape of a Suraqah bin Malik bin Ju`shum, man from Bani Mudlij, Shaytan said to idolators, `None will defeat you this day, and I will help you.' When the two armies stood face to face, the Messenger of Allah took a handful of sand and threw it at the faces of the idolators, causing them to retreat. Jibril, peace be upon him, came towards Shaytan, but when Shaytan, while holding the hand of a Mushrik man, saw him, he withdrew his hand and ran away with his soldiers. That man asked him, `O Suraqah! You claimed that you are our neighbor' He said,

﴿إِنِّي أَرَى مَا لاَ تَرَوْنَ إِنِّي أَخَافُ اللَّهَ وَاللَّهُ شَدِيدُ الْعِقَابِ﴾

(Verily, I see what you see not. Verily, I fear Allah for Allah is severe in punishment)

Shaytan said this when he saw the angels.''
