Narrated Hudhayfah ibn Usayd:
Allah's Apostle (peace_be_upon_him) said: When the drop of (semen) remains in the womb for forty or fifty (days) or forty nights, the angel comes and says: My Lord, will he be good or evil? And both these things would be written. Then the angel says: My Lord, would he be male or female? And both these things are written. And his deeds and actions, his death, his livelihood; these are also recorded. Then his document of destiny is rolled and there is no addition to and subtraction from it.
Narrated Jabir ibn Abdullah:
Suraqah ibn Malik ibn Ju'shum came and said: Allah's Apostle (peace_be_upon_him), explain our religion to us (in a way) as if we have been created just now. Whatever deeds we do today, is it because of the fact that the pens have dried (after recording them) and the destinies have begun to operate or these have effects in future? Thereupon he said: The pens have dried and destinies have begun to operate (Suraqah b. Malik) said: If it is so, then what is the use of doing good deeds?
Zuhayr said: Then AbuzZubayr said something but I could not understand that and I said: What did he say? Thereupon he said: Act for everyone is facilitated what he intends to do.
Narrated Imran ibn Husayn:
AbulAswad reported that Imran asked me: What is your view what the people do today in the world, and strive for, is it something decreed for them or preordained for them or will their fate in the Hereafter be determined by the fact that their Prophets brought them teaching which they did not act upon? I said: Of course, it is something which is predetermined for them and preordained for them.
He (further) said: Then, would it not be an injustice (to punish them)? I felt greatly disturbed about that, and said: Everything is created by Allah and lies in His Power. He will not be questioned as to what He does, but they will be questioned. Thereupon he said to me: May Allah have mercy upon you, I only meant to ask you in order to test your intelligence.
Two men of the tribe of Muzaynah came to Allah's Apostle (peace_be_upon_him) and said: Allah's Apostle, what is your opinion? That which the people do in the world and strive for, is something decreed for them, something preordained for them? And will their fate in the Hereafter be determined by the fact that their Prophets brought them teachings which they did not act upon and thus they deserve of punishment?
Thereupon, he said: Of course, it happens as it is decreed by Destiny and preordained for them, and this view is confirmed by this verse of the Book of Allah, the Exalted and Glorious: "Consider the soul and Him Who made it perfect, then breathed into it its sin and its piety." (91:8).
Narrated AbuHurayrah:

Abdullah heard Allah's Apostle (peace_be_upon_him) as saying: Verily, the hearts of all the sons of Adam are between the two fingers out of the fingers of the Compassionate Lord as one heart.

A child died and I said: There is happiness for this child who is a bird from amongst the birds of Paradise.

Narrated Abdullah:
Umm Habibah, the wife of Allah's Apostle (peace_be_upon_him) said: O Allah, enable me to derive benefit from my husband, the Messenger of Allah (May peace be upon him), and from my father, AbuSufyan, and from my brother, Mu'awiyah. Allah's Apostle (peace_be_upon_him) said: You have asked from Allah about durations of life already set, the length of days already allotted, and the sustenances, the share of which has been fixed. Allah will not do anything before its due time, nor will He delay anything beyond its due time. And if you were to ask Allah to provide you with refuge from the torment of the Hell-Fire, or from the torment of the grave, it would have good in store for you and better things for you also.
He (the narrator) added: Mention was made before him of monkeys, and Mis'ar (one of the narrators) said: I think that (the narrator) also (mentioned) swine which had suffered metamorphosis. Thereupon he (the Holy Prophet) said: Verily, Allah did not cause the race of those which suffered metamorphosis to grow, or they were not survived by young ones. Monkeys and swine have been in existence even before (the metamorphosis of the human beings).
Narrated AbuHurayrah:
Allah's Apostle (peace_be_upon_him) said: A strong believer is better and is more lovable to Allah than a weak believer, and there is good in everyone, (but) cherish that which gives you benefit (in the Hereafter) and seek help from Allah and do not lose heart, and if anything (in the form of trouble) comes to you, don't say: If I had not done that, it would not have happened so and so, but say: Allah did that what He had ordained to do and your "if" opens the (gate for the Satan.
