2ـ مُعَاوِيَةُ بْنُ عَمَّارٍ عَنْ أَبِي عَبْدِ الله (عَلَيْهِ السَّلاَم) قَالَ سَأَلْتُهُ عَنِ الرَّجُلِ يَسْعَى بَيْنَ الصَّفَا وَالْمَرْوَةِ رَاكِباً قَالَ لا بَأْسَ وَالْمَشْيُ أَفْضَلُ.
2. Mu‘awiyah ibn ‘Ammar has said the following: “I once asked abu ‘Abd Allah (a.s.), about a man who performs Sa‘y between al-Safa’ and al-Marwah riding. He (the Imam) said, ‘It is not harmful but walking is more virtuous.’”
