قَالُوا۟ نَحْنُ أُو۟لُوا۟ قُوَّةٍۢ وَأُو۟لُوا۟ بَأْسٍۢ شَدِيدٍۢ وَٱلْأَمْرُ إِلَيْكِ فَٱنظُرِى مَاذَا تَأْمُرِينَ
They said: We are lords of might and lords of great prowess, but it is for thee to command; so consider what thou wilt command.

Sahih al-Bukhari
Hajj (Pilgrimage)
Chapter: Whosoever sent the weak early (from Al-Muzdalifa to Mina)
Narrated Salim:
`Abdullah bin `Umar used to send the weak among his family early to Mina. So they used to depart from Al-Mash'ar Al-Haram (that is Al-Muzdalifa) at night (when the moon had set) and invoke Allah as much as they could, and then they would return (to Mina) before the Imam had started from Al- Muzdalifa to Mina. So some of them would reach Mina at the time of the Fajr prayer and some of them would come later. When they reached Mina they would throw pebbles on the Jamra (Jamrat-Al- `Aqaba) Ibn `Umar used to say, "Allah's Messenger (ﷺ) gave the permission to them (weak people) to do so."
