Allah reminds of His measuring and deciding the destiny of all things before 
He created the creation,
[مَآ أَصَابَ مِن 
مُّصِيبَةٍ فِى الاٌّرْضِ وَلاَ فِى أَنفُسِكُمْ]
(No calamity occurs on the earth nor in yourselves) meaning, `there is 
nothing that touches you or happens in existence,'
[إِلاَّ فِى كِتَـبٍ 
مِّن قَبْلِ أَن نَّبْرَأَهَآ]
(but it is inscribed in the Book of Decrees before We bring it into 
existence.) meaning, `before We created the creation and started life.' Qatadah 
commented on this Ayah,
[مَآ أَصَابَ مِن 
مُّصِيبَةٍ فِى الاٌّرْضِ]
(No calamity occurs on the earth) refers to famine, while,
[وَلاَ فِى 
أَنفُسِكُمْ]
(or nor in yourselves) refers to suffering and diseases.'' He also said, "We 
were told that every person who suffers a prick of a thorn, a twisted ankle, or 
a bleeding vein, has it occur on account of his sins. What Allah forgives is 
even more.'' This great, honorable Ayah provides clear evidence to the 
misguidance of the cursed Qadariyyah sect, who deny Allah's Preordaihnent and 
His knowledge of everything before it occurs. Imam Ahmad recorded that `Abdullah 
bin `Amr bin Al-`As said, "I heard the Messenger of Allah say,
«قَدَّرَ اللهُ 
الْمَقَادِيرَ قَبلَ أَنْ يَخْلُقَ السَّموَاتِ وَالْأَرْضَ بِخَمْسِينَ أَلْفَ 
سَنَة»
(Allah ordained the measures (of everything) fifty thousand years before He 
created the heavens and the earth.)'' Muslim collected this Hadith in his Sahih 
with the addition:
«وَكَانَ عَرْشُهُ 
عَلَى الْمَاء»
(And His Throne was over the water.) At-Tirmidhi also collected it and said, 
"Hasan Sahih.'' Allah's statement,
[إِنَّ ذلِكَ عَلَى 
اللَّهِ يَسِيرٌ]
(Verily, that is easy for Allah.) means that He knows all things before they 
occur, and He records them exactly as they will occur when they occur, and this 
is easy for Him. Verily, Allah knows what happened, what will happen and what 
did not happen, and what shape and form it will take if it were to happen.
