Surah Al A'raf Tafseer

لاأُقَطِّعَنَّ أَيْدِيَكُمْ وَأَرْجُلَكُم مِّنْ خِلأَفٍ

"Surely, I will cut off your hands and your feet from opposite sides."

by cutting the right hand and the left leg or the opposite,

ثُمَّ لاُصَلِّبَنَّكُمْ أَجْمَعِينَ

"then I will crucify you all."

just as he said in another Ayah,

فِى جُذُوعِ النَّخْلِ

"Fi the trunks of date palms." (20:71)

Fi in this Ayah means "on".

Ibn Abbas said that Fir`awn was the first to crucify and cut off hands and legs on opposite sides.

The magicians said,

قَالُواْ إِنَّا إِلَى رَبِّنَا مُنقَلِبُونَ
