Can you kindly explain the following with daleels?

1. Does a child's soul exist in barzakh before birth?

2. Will adhaabul qabr occur in the barzakh?

Man’s life is divided into three sections:

1. The life of this world, which ends with death.
2. The life in al-barzakh, which starts after death and ends when the Hour begins.
3. The life of the Hereafter, which begins after the people are raised from their graves, and is spent either in Paradise (we ask Allah of His Bounty) or in Hell (we seek refuge with Allah).
