Read all Ahadith in chapters on al-qadar by jami al tirmizi

Abu Hurairah narrated: The Messenger of Allah(s.a.w) came out to us while we were discussing about Al-Qadar. He became angry such that his face became red, as if a pomegranate was bursting through his cheeks. He said: 'Is this what I ordered you to do?' - or: 'Is this what I have been sent to you with? The people before you were only ruined when they differed about this matter. I order you [I order you] to not debate about it.' . (Daif))

Abu Hurairah narrated that the Prophet(S.A.W) said: Adam and Musa argued, Musa said: O Adam! You are the one that Allah created with His Hand, and blew into you of His Spirit, and you misled the people and caused them to be expelled from Paradise.' So Adam said: 'You are Musa, the one Allah selected with His Speech! Are you blaming me for something I did which Allah had decreed for me, before creating the heavens and the earth?' He said: So Adam confuted Musa.

Asim bin 'Ubaidullah said: ' I heard Salim bin 'Abdullah narrating a Hadith from his father who said: 'Umar said : O Messenger of Allah! Do you see that what we do is a new matter- or a matter initiated – or it is a matter already concluded?” He (s.a.w) said: “ O Ibn Al-Khattab! It is a matter already concluded. For everyone is suited (for that for which he is created). As for one who is among the people of happiness, then he works for happiness, and as for the one who is among the people of misery, then he works for his misery.” (Hasan)

Ali narrated: We were with the Messenger of Allah (s.a.w) and he was scraping the ground, when he raised his head to the heavens, then said: 'There is not one of you but (his place) is known' – Waki said: 'His place has been decreed (be it) in the Fire, and (or) his place in Paradise.' They said: 'Shall we not rely upon this O Messenger of Allah?' He said: 'No. Work, for everyone is facilitated for what he was created.'”(Sahih)

Abdullah bin Mas'ud said: The Messenger of Allah (s.a.w) narrated to us - and he is the truthful and entrusted one: 'Indeed the creation of one of you is gathered inside his mother in forty days. Then, for a similar period, he is a clot. Then, for a similar period, he is a piece of flesh. Then Allah sends the angel to him to blow the soul into him, and he is ordered to write four (things): To write his provision, his life-span, his works, and whether he will be wretched or happy. By the One besides Whom there is none other worthy of worship! One of you will do deeds of the people of Paradise, until there is between him and it but a forearm span, then he is overcome by what is written for him, and he is sealed off with the deeds of the people of the Fire, so that he enters it. And indeed one of you will do deeds of the people of the Fire, until there is between him and it but a forearm span, then he is overcome by what is written for him, and he is sealed off with the deeds of the people of Paradise, so that he enters it.'

Abu Hurairah narrated that the Messenger of Allah (s.a.w) said: Every child is born upon the Millah, then his parents make him a Jew, a Christian, or a idolater. It was said: O Messenger of Allah! What about those who die before that? He said: Allah knows best what they would have done.

Salman narrated that the Messenger of Allah (s.a.w) said: Nothing turns back the Decree except supplication, and nothing increases the life-span except righteousness.

Anas narrated: The Messenger of Allah (s.a.w) would often say: Ya Muqallibal-qulub, thabbit qalbi 'ala dinik('O Changer of the Hearts! Strengthen my heart upon Your Religion.)' So I said: 'O Prophet of Allah! We believe in you and what you have come with, but do you fear for us?' He said: 'Yes. Indeed the hearts are between two Fingers of Allah's Fingers, He changes them as He wills.'

Abdullah bin 'Amr narrated: The Messenger of Allah (s.a.w) came out to us with two books in hand. And he said: 'Do you know what these two books are?' We said: 'No, O Messenger of Allah ! Unless you inform us.' He said about the one that was in his right hand: 'This is a book from the Lord of the worlds, in it are the names of the people of Paradise, and the name of their fathers and their tribes. Then there is a summary at the end of them, there being no addition to them nor deduction from them forever.' Then he said about the one that was in his left: 'This is a book from the Lord of the worlds, in it are the names of the people of Fire, and the name of their fathers and their tribes. Then there is a summary at the end of them, there being no addition to them nor deduction from them forever.' The companions said: 'So why work O Messenger of Allah! Since the matter is already decided (and over)?' He said: 'Seek to do what is right and draw nearer, for indeed the inhabitant of Paradise, shall have his work sealed off with the deeds of the people of Paradise, whichever deeds he did. And indeed the inhabitant of Fire, shall have his work sealed off with the deeds of the people of Fire, whichever deeds he did.' Then the Messenger of Allah motioned with his hands, casting them down and said: 'Your Lord finished with the slaves, a group in Paradise, and a group in the Blazing Fire.'

Anas narrated that the Messenger of Allah (s.a.w) said: When Allah wants good for a slave, He puts him in action. It was said: How does he put him in action O Messenger Of Allah? He said: By making him meet up with the righteous deeds before death.
