It was narrated that Ibn Abbas said:"When the Prophet and his Companions came to Makkah, the idolaters said: 'The fever of Yathrib has weakened them, and they have suffered a great deal because of it.' Allah informed His Prophet about that, so he told his Companions to walk rapidly, and to walk (at a normal pace) between the two corners, and the idolaters were on the side of the Stone. They said: 'They are stronger than such and such.'"
أَخْبَرَنِي مُحَمَّدُ بْنُ سُلَيْمَانَ، عَنْ حَمَّادِ بْنِ زَيْدٍ، عَنْ أَيُّوبَ، عَنِ ابْنِ جُبَيْرٍ، عَنِ ابْنِ عَبَّاسٍ، قَالَ لَمَّا قَدِمَ النَّبِيُّ صلى الله عليه وسلم وَأَصْحَابُهُ مَكَّةَ قَالَ الْمُشْرِكُونَ وَهَنَتْهُمْ حُمَّى يَثْرِبَ وَلَقَوْا مِنْهَا شَرًّا فَأَطْلَعَ اللَّهُ نَبِيَّهُ عَلَيْهِ الصَّلاَةُ وَالسَّلاَمُ عَلَى ذَلِكَ فَأَمَرَ أَصْحَابَهُ أَنْ يَرْمُلُوا وَأَنْ يَمْشُوا مَا بَيْنَ الرُّكْنَيْنِ وَكَانَ الْمُشْرِكُونَ مِنَ نَاحِيَةِ الْحِجْرِ فَقَالُوا لَهَؤُلاَءِ أَجْلَدُ مِنْ كَذَا .
