Allah emphasizes the enmity that the hypocrites have for the Prophet

If a blessing, such as victory and triumph over the enemies, is given to the Prophet , thus pleasing him and his Companions, it grieves the hypocrites,

وَإِن تُصِبْكَ مُصِيبَةٌ يَقُولُواْ قَدْ أَخَذْنَا أَمْرَنَا مِن قَبْلُ

In the ninth verse (51), Allah Ta` ala has instructed the Holy Prophet ﷺ and Muslims, that they should not allow themselves to be affected by things like that said by the hypocrites and that they must always keep reality as it is before them. The words of the Holy Qur'an are:. قُل لَّن يُصِيبَنَا إِلَّا مَا كَتَبَ اللَّـهُ لَنَا هُوَ مَوْلَانَا ۚ وَعَلَى اللَّـهِ فَلْيَتَوَكَّلِ الْمُؤْمِنُونَ ﴿51﴾ (Say, "Nothing , can ever reach us except what Allah has written for us. He is our Master. And in Allah alone the believers must place their trust" ). In other words, the Holy Prophet ﷺ is being asked that he should tell those, who worship material causes such as these, that they were in a serious deception. These material causes were no more than a curtain. The power that moves inside them belongs to none but Allah. Whatever happens to us is exactly whatever Allah has written for us - and He, is our Master, Guardian and Helper. And Muslims must place their real trust in Him alone. Consequently, they must see material causes as no more than effective agents and signs while never taking them to be the real dispensers of any good or evil.

Belief in Destiny includes Management of affairs: Giving Inaction or Mismanagement the name of Trust is Wrong
