Sahih Muslim Book - 15, Hadith - 3143

وَحَدَّثَنِى سَلَمَةُ بْنُ شَبِيبٍ حَدَّثَنَا الْحَسَنُ بْنُ أَعْيَنَ حَدَّثَنَا مَعْقِلٌ - وَهُوَ ابْنُ عُبَيْدِ اللَّهِ الْجَزَرِىُّ - عَنْ أَبِى الزُّبَيْرِ عَنْ جَابِرٍ قَالَ قَالَ رَسُولُ اللَّهِ -صلى الله عليه وسلم- « الاِسْتِجْمَارُ تَوٌّ وَرَمْىُ الْجِمَارِ تَوٌّ وَالسَّعْىُ بَيْنَ الصَّفَا وَالْمَرْوَةِ تَوٌّ وَالطَّوَافُ تَوٌّ وَإِذَا اسْتَجْمَرَ أَحَدُكُمْ فَلْيَسْتَجْمِرْ بِتَوٍّ ».

It was narrated that Jabir said: “The Messenger of Allah (SAW) said: ‘The number of stones used for cleaning oneself (after defecating) is odd, and the number of stones used for stoning the Jamrah is odd, and the number of times for Sai between Al-Safa and Al-Marwah is odd, and the number of circuits around the Kabah is odd, so when one of you cleans himself with stones, let him use odd number of stones. ’”
