(17) باب الاِخْتِلاَفِ عَلَى عَائِشَةَ فِي إِحْيَاءِ اللَّيْلِ . أ }
It was narrated from Anas bin Malik that:
The Messenger of Allah (ﷺ) entered the masjid and saw a rope tied between two pillars. He said: "What is this?" They said: "It is for Zainab when she prays; if she gets tired she holds on to it." The Prophet (ﷺ) said: "Untie it. Let any one of you pray as long as he has energy, and if he gets tired let him sit down."
