Since then quantum mechanics has become an important part of atomic physics.
The following traditions from al-Shaykh al-Saduq's al-Tawhid, pp.360-362 (Jami'at al-mudarrisin fi al-Hawzat al-'Ilmiyyah, Qum), explain the Shi'ah position: ...Al-Imam al-Baqir (A) and al-Imam al-Sadiq (A) said: "Indeed God is of greater mercy than that He should coerce His creatures into sin and then punish them for that; and God is of greater might than that He should will something and it should fail to happen." They were asked, "Is there any third position between absolute predestination (jabr) and absolute freedom (qadar)?" They said: "Yes, vaster than the space between the heaven and the earth." ...Muhammad ibn 'Ajun says: "I asked Abu 'Abd Allah (A), 'Has God left men free [to do what they may like]?' He replied, 'God is nobler than that He should leave it upto them [to do whatever they may like].' I said, 'Then God has imposed their deeds upon them?' He said, 'God is more just than that He should coerce a creature into committing some act and then punish him on its account.' Al-Hasan ibn 'Ali al-Washsha' says, "I asked al-Imam al-Rida (A) whether God has given men total freedom in their acts.
He said, 'God is mightier than that.' I said, 'Then, has He coerced them into sins?' He replied, 'God is more just and wiser than that He should do such a thing.' Then he added, 'God, the Almighty, has said, "O son of Adam!
I deserve more credit in your virtues than yourself, and you deserve more discredit for your sins than I; you commit sins with the power I have given you."''' ...Al-Mufaddal ibn 'Umar reports that al-Imam Abu 'Abd Allah (al-Sadiq) (A) said, "Neither total predetermination (jabr), nor total freedom (tafwid), but a position intermediate between the two (amr bayna amrayn)." I said, "What is amr bayna amrayn?" He replied, "It is as if you see someone committing a sin.
You stop him, but he does not desist. So you leave him alone.
