“If I go quickly between Safa and Marwah, that is because I saw the Messenger of Allah ﷺ going quickly, and if I walk that is because I saw the Messenger of Allah ﷺ walking, even though I am an old man.” (Using translation from Ibn Mājah 2988)   

لِابْنِ عُمَرَ فِي السَّعْيِ بَيْنَ الصَّفَا وَالْمَرْوَةِ أَرَاكَ تَمْشِي وَالنَّاسُ يَسْعَوْنَ؟ قَالَ إنْ أَمْشِي فَقَدْ رَأَيْتُ رَسُولَ اللهِ ﷺ يَمْشِي وَإنْ أَسْعَى فَقَدْ رَأَيْتُ رَسُولَ اللهِ ﷺ يَسْعَى وَأَنَا شَيْخٌ كَبِيرٌ
