Musannaf Ibn Abi Shaybah 3531 — When a child is told to pray

Ja'far reports from his father that Ali bin al-Husayn used to command the children to pray Zuhr and Asr together, and Maghrib and Isha together. Someone said to him: "In this way they will be praying outside the prayer's time." Ali bin al-Husayn said: "This is better than them sleeping through it without praying."
