Ibn Mas'ud narrated:
"The Rasul of Allah (saw) stood among us and said: 'One thing does not infect another.' So a Bedouin asked: 'O Rasul of Allah! If a camel gets mangy glands and we leave it at the resting place of camels, wont all of the other camels get mange?' The Rasul of Allah (saw) said: 'Who caused the first one to get mange? There is no 'Adwa nor safar (no disease is conveyed from the sick to the healthy without the permission of Allah) Allah created every soul and determined its life, its provision, and its afflictions.'"
Abu Hurairah (ra) narrated that the Rasul of Allah (saw) said: Nobody can enter paradise through their good deeds or prayers. Thereupon his companions asked, “Not even you o Rasul of Allah?” “Not even me!” said the Rasul of Allah, “I shall only enter paradise through the mercy of Allah. So stay away from going to extremes in your work and worship.”
Abdullah ibn Amr reported: The Rasul of Allah (saw) said, “Verily, Allah Almighty created his creation in darkness and he cast over them his light. Whoever is touched by that light is guided, and whoever misses it is astray. Thus, I say the pens have been dried upon the knowledge of Allah.”
Zaid bin Thabit narrates: “I heard the Rasul of Allah (saw) say: If Allah were to punish the inhabitants of His heavens and of His earth, he would do so and He would not be unjust towards them. And if He were to have mercy on them, His mercy would be better for them than their own deeds. If you had the equivalent of Mount Uhud which you spent in the cause of Allah, that would not be accepted from you until you believed in the Divine Decree and that whatever has befallen you, could not have passed you by; and whatever has passed you by, could not have befallen you; and that if you were to die believing anything other than this, you would enter Hell.”
I hope these verses from the Quran and Hadith from the collection called Qutubu Sittah will help you gain a greater perspective on the matter.
These are the universal truths to which the Rasul and Nabi of Allah (saw) invited us to have faith in. I hope we may be of the grateful who are able to duly evaluate and not of the ungrateful ones.
Every one will inescapably and inevitably face the consequences of their actions. This is the unalterable law of the Sunnatullah.
FAQ Regarding the topic of fate:
Since my fate has already been predetermined and since “what will be will be and what won’t be can’t ever be” then what’s the point in doing anything at all?
If not doing anything at all is a part of your fate then you may certainly go ahead and not do anything. Bu if you’re destined to do something then it will be eased for you and you will inevitably be drawn to doing it.
If Allah has determined for me to go to hell and has eased the deeds of hell for me then what’s my fault?
The sovereign One may administer His sovereignty however he likes. Just as you assume the right to manage your possessions however you like and should you be prevented from doing so you would complain that your rights are being breached, Allah the Absolute owner and creator of the universe has the right to do as he wills, however he wills, without any conditions.
