The virtue of dust in the cause of Allah

Sayyiduna Abu al-Darda' (may Allah be pleased with him) reports this as a marfu' hadith from the Prophet (peace and blessings be upon him): The Prophet (peace and blessings be upon him) said: "Allah Almighty will not combine the dust of the path of Allah and the smoke of Hell in the belly of a man. Whoever's feet become dusty in the path of Allah, Allah Almighty will make his whole body forbidden to Hell. Whoever fasts one day in the path of Allah, Allah Almighty will remove Hell from him by a distance of a thousand years, a distance covered by a swift rider. Whoever receives a wound in the path of Allah will be sealed with the seal of the martyrs, and that wound will be a light for him on the Day of Resurrection, its colour like the colour of saffron and its fragrance like the fragrance of musk, by which all the earlier and later people will recognise him, and they will say: So-and-so bears the seal of the martyrs. And whoever fights in the path of Allah for as long as the interval between two milkings of a she-camel, Paradise becomes obligatory for him."
Ahmad recorded it, and its narrators are thiqat (trustworthy), except that Khalid bin Duraik did not hear from Sayyiduna Abu al-Darda' (may Allah be pleased with him), nor did he meet him.

Abu al-Musabbih narrates: Once we were travelling through the pass of Qalamtah when the commander, Malik bin Abdullah al-Khath'ami, called out loudly to a man who was leading his horse along the mountainside, and said: O Abu Abdullah! Why do you not ride? He said: I heard the Prophet (peace and blessings be upon him) say: "Whoever's feet become dusty in the path of Allah, both of them will be forbidden to Hell."
Ahmad recorded it through two chains, and Abu Ya'la also recorded it; in one of the two chains his wording is: "for an hour of the day." The narrators of Ahmad in one of the two chains are the narrators of the Sahih, except Abu al-Musabbih, who is thiqah (trustworthy). In the other narration Ahmad also recorded the words: "for an hour of the day."

He said to him: Ride, for I see that your animal is strong-backed (i.e., fit for riding). He replied: I heard the Prophet (peace and blessings be upon him) say: "No servant's feet become dusty in the path of Allah but Allah Almighty makes Hell forbidden to them." The narrator says: Malik dismounted, and the other people also dismounted and began walking; no day was seen with more people walking on foot than that day.

He replied: The Prophet (peace and blessings be upon him) said: "Whoever's feet become dusty in the path of Allah, Allah Almighty makes that person forbidden to Hell."

When the man came, the Prophet (peace and blessings be upon him) asked him: "What is the reason you were keeping away from the road?" He replied: I dislike the dust. The Prophet (peace and blessings be upon him) said: "Do not keep away from it. By the One in whose Hand is my soul, it (i.e., the dust of the path of Allah) is the dharirah (a particular kind of fragrance) of Paradise."
