´Sufyan narrated from Habib bin Abi Thabit, from Muhammad bin Ali, from his father, from his grandfather, that:` The Prophet (ﷺ) got up at night and cleaned his teeth, then he prayed two rak'ahs, then he slept. Then he got up and cleaned his teeth, then he performed wudu and prayed two rak'ahs, until he had prayed six. Then he prayed witr with three rak'ahs, and prayed two rak'ahs.

Narrated Ibn Abbas: I spent a night with my maternal aunt Maimunah. The Messenger of Allah ﷺ came after the evening has come. He asked: Did the boy pray ? She said: Yes. Then he lay down till a part of night had passed as much as Allah willed; he got up, performed ablution and prayed seven or five rak'ahs, observing witr with them. He uttered the salutation only in the last of them.
Shaykh Umar Farooq Saeedi
1356. Commentary: Benefit: It is specifically the responsibility of the household members, especially the mother, to habituate young children to prayer (salah) and other virtuous deeds, and it is the right of the father or guardian to remain vigilant regarding these matters or to question them about it.
