Al-Qadr is the concept that Allah knows everything and has already decided everything that will happen. This is called predestination.
Al-Qadr is linked to the six beliefs of Sunni Islam. This is because it shows that Allah is omniscient, meaning ‘knowing everything’, and omnipotent, meaning ‘having unlimited power.’ In the Hadith, Ali speaks of predestination:
There is not one amongst you who has not been allotted his seat in Paradise or Hell. They said: Allah’s messenger, then why should we perform good deeds, why not depend upon our destiny? Thereupon he said, no, do perform good deeds, for everyone is facilitated in that for which he has been created.Sahih Muslim 2647
Although al-Qadr is a key belief within Islam . Muslims believe that nothing can happen without the will of Allah. However, Al-Qadr does not mean that the choices people make are not free choices. Instead, it means that Allah knows what choices people are going to make before they are made.
There is evidence of al-Qadr in the Qur’an: The Lord has created and balanced all things and has fixed their destinies and guided them. (Qur’an 87:2)
The belief in free will is essential in Islam. This is because, for Muslims, life is a test from Allah. Therefore, all human beings must make their own decisions, and they will be judged on those decisions by Allah. On the Day of Judgement, God will reward those who have had faith and done good deeds and punish those who have not. So, God judges people on their choices, not on the destiny already decided for them. The Qur’an confirms this:
Whoever does righteousness – it is for his [own] soul; and whoever does evil [does so] against it. And your Lord is not ever unjust to [his] servants.Qur’an 41:46
Muslims use the term ‘insha’Allah’ frequently in conversation to express belief in al-Qadr. Insha’Allah means ‘if God is willing’ or ‘if God wills it to be so’.
