Silsilat al-Ahadith al-Sahihah

It is narrated from Sayyiduna Abu Sa'id Khudri (may Allah be pleased with him) that the Messenger of Allah (peace and blessings of Allah be upon him) stood up and performed the Fajr prayer, and he (Abu Sa'id) was behind him. The Prophet recited (Qur'an), but the recitation became confused for him. When he finished the prayer, the Prophet (peace and blessings of Allah be upon him) said: "If only you had seen me and Iblis. I extended my hand and kept choking him, until I felt the coolness of his saliva between my thumb and the finger next to it. If it were not for the supplication of my brother Sulaiman (peace be upon him), he would have been left tied to one of the pillars of the mosque until morning, and the children of Madinah would have played with him. Whoever among you is able that nothing should come between him and his qiblah (direction of prayer) during prayer, then let him do so."
