وَعَنْ جَابِرٍ قَالَ: قَالَ رَسُولُ اللَّهِ صَلَّى اللَّهُ عَلَيْهِ وَسَلَّمَ: «الِاسْتِجْمَارُ تَوٌّ وَرَمْيُ الْجِمَارِ توٌّ وَالسَّعْيُ بَيْنَ الصَّفَا وَالْمَرْوَةِ تَوٌّ وَالطَّوَافُ تَوٌّ وَإِذَا اسْتَجْمَرَ أَحَدُكُمْ فَلْيَسْتَجْمِرْ بِتَوٍّ» . رَوَاهُ مُسْلِمٌ
English Translation
Jabir reported God’s messenger as saying, “Cleaning oneself with stones (Isijmar is the word used, and Taj al-Arus suggests that here its meaning is throwing pebbles ; but as ramy al-jimar occurs in the next phrase, it seems better to translate it as above to avoid saying the same things twice. Cf. p. 74, lines 9 f.) is with an odd number, throwing pebbles at the jamras is with an odd number, running between as-Safa and al-Marwa is with an odd number, and the circumambulation is with an odd number. When one of you cleans himself with stones he should do so with an odd number.” Muslim transmitted it.
