4ـ الْحُسَيْنُ بْنُ مُحَمَّدٍ عَنْ مُعَلَّى بْنِ مُحَمَّدٍ عَنْ بَعْضِ أَصْحَابِنَا عَنْ أَبَانٍ عَنْ عَبْدِ الرَّحْمَنِ عَنْ أَبِي عَبْدِ الله (عَلَيْهِ السَّلاَم) قَالَ لا يُجْلَسُ بَيْنَ الصَّفَا وَالْمَرْوَةِ إِلاَّ مِنْ جَهْدٍ.
4. Al-Husayn ibn Muhammad has narrated from Mu‘alla’ ibn Muhammad, from certain persons of our people, from Aban, from ‘Abd al- Rahman who has said the following: “Abu ‘Abd Allah (a.s.), has said, ‘You must not sit down between al-Safa’ and al-Marwah unless you are very exhausted.’”
