“Once, we visited abu ‘Abd Allah (a.s.), and he asked us, ‘Does anyone of you have anything of the knowledge of my uncle, Zayd ibn Ali?’ A man from the group said, ‘I have something of the knowledge of your uncle. Once, we were in the presence of Imam one night in the house of Mu‘awiyah ibn Ishaq al-Ansariy when he said, “Allow us to visit al-Sahlah Masjid to perform Salah (prayer).’” Abu ‘Abd Allah (a.s.), then asked, ‘Did he do so?’ He (the man) replied, ‘Something came up that prevented him from visiting al-Sahlah Masjid.’ The Imam then said, ‘By Allah, had he sought refuge with Allah therein for a year he would have given him such refuge. You should take notice that it is the house of prophet Idris. Therein he did his sewing works. From this place Ibrahim started his journey to Yemen, where al-‘Amaliqah people has settled down. Dawud began his move against Jalut (Goliath) from this place. In it, there is the green stone on which every prophet’s picture exists. From under this stone the clay of every prophet was taken and it is the place where the rider disembarks for rest.’ It was asked, ‘Who is the rider?’ The Imam replied, ‘He is al- Khadir.’”
