Hadith 2419مُحَمَّدُ بْنُ يَحْيَى عَنْ عَلِيِّ بْنِ إِبْرَاهِيمَ الْجَعْفَرِيِّ رَفَعَهُ قَالَ سَأَلْتُ الصَّادِقَ ( عليه السلام ) مَتَى أَضْرِبُ دَابَّتِي تَحْتِي فَقَالَ إِذَا لَمْ تَمْشِ تَحْتَكَ كَمَشْيَتِهَا إِلَى مِذْوَدِهَا .
6. Muhammad ibn Yahya has narrated from Ali ibn Ibrahim al-Ja‘fariy in a marfu‘ manner has said the following: “I once asked al-Sadiq (a.s.), ‘When can I hit my stumper?’ He (the Imam) said, ‘You can do so when you are riding and it does not walk as it does when going to its manger, its feeding place.’”
