Mishkat al-Masabih 29 Excellent Qualities and Description of the Prophet كتاب الفضائل والشمائل 52

وَعَنْ جَابِرٌ أَنَّ النَّبِيَّ صَلَّى اللَّهُ عَلَيْهِ وَسَلَّمَ لَمْ يَسْلُكْ طَرِيقًا فَيَتْبَعُهُ أَحَدٌ إِلَّا عرفَ أَنه قد سلكه من طيب عرقه – أَوْ قَالَ: مِنْ رِيحِ عَرَقِهِ – رَوَاهُ الدَّارِمِيُّ

Jabir said the Prophet never walked along a road without one who came along afterwards knowing he had walked along it because of his sweet odour. Or he said, “because of the fragrance of his sweat.” Darimi transmitted it.
