Sunan of Abu Dawood Book 11, Hadith 1886

حَدَّثَنَا مُسَدَّدٌ، حَدَّثَنَا حَمَّادُ بْنُ زَيْدٍ، عَنْ أَيُّوبَ، عَنْ سَعِيدِ بْنِ جُبَيْرٍ، أَنَّهُ حَدَّثَ عَنِ ابْنِ عَبَّاسٍ، قَالَ قَدِمَ رَسُولُ اللَّهِ صلى الله عليه وسلم مَكَّةَ وَقَدْ وَهَنَتْهُمْ حُمَّى يَثْرِبَ فَقَالَ الْمُشْرِكُونَ إِنَّهُ يَقْدَمُ عَلَيْكُمْ قَوْمٌ قَدْ وَهَنَتْهُمُ الْحُمَّى وَلَقُوا مِنْهَا شَرًّا فَأَطْلَعَ اللَّهُ سُبْحَانَهُ نَبِيَّهُ صلى الله عليه وسلم عَلَى مَا قَالُوهُ فَأَمَرَهُمْ أَنْ يَرْمُلُوا الأَشْوَاطَ الثَّلاَثَةَ وَأَنْ يَمْشُوا بَيْنَ الرُّكْنَيْنِ فَلَمَّا رَأَوْهُمْ رَمَلُوا قَالُوا هَؤُلاَءِ الَّذِينَ ذَكَرْتُمْ أَنَّ الْحُمَّى قَدْ وَهَنَتْهُمْ هَؤُلاَءِ أَجْلَدُ مِنَّا ‏.‏ قَالَ ابْنُ عَبَّاسٍ وَلَمْ يَأْمُرْهُمْ أَنْ يَرْمُلُوا الأَشْوَاطَ إِلاَّ إِبْقَاءً عَلَيْهِمْ ‏.‏

Ibn ‘Abbas said The Apostle of Allaah(ﷺ) came to Makkah while the fever of Yathrib (Medina) had weakened them. Thereupon the disbelievers said "The people whom the fever has weakened and who suffer misery at Medina are coming to you." Allaah, the exalted, informed the Prophet (ﷺ) of what they had said. He, therefore, ordered them to perform ramal (walk proudly with swift pace) in first three circuits and walk ordinarily between the two corners (Yamani Corner and the Black Stone). When they saw them the believers walking proudly, they said" These are the people about whom you mentioned that the fever had weakened them, but they are more vigorous than us." Ibn ‘Abbas said "He did not order them to walk proudly in all circuits (of the circumambulation) out of mercy upon them."
