There are many Prophetic sayings about the cleanliness of roads. The Prophet, peace and blessings be upon him, tells in detail about the wideness of roads, the construction of roads, the maintenance of their cleanliness and protecting them against highwaymen.

Through ablution or bathing to prepare for the prayers, the body and the limbs are purified from dirt and impurities.

In a hadith reported by Abu Hurayra, God's Messenger, may peace and blessings be upon him, said:

Fussilat (Clearly Expounded) - Chapter 41: Verse 39 (partial)

"Among His signs is that you see the earth laid bare and then when We send down water on it, it quivers and swells."

The Prophet (peace be upon him) said that fasting is a protection from the Hell-fire: "Fasting is a shield from the Hell-fire like one of your shields shielding you while fighting" [Ahmad, Nasai].

lbn al-Qayyim noted some of the beneficial and important aspects of fasting when he wrote,

Ibn Abbas reports that, while he was once in retreat (itikaf) to the mosque in the Masjid al-Nabi (The Messenger’s mosque) a certain man came to him, greeted him and sat down. Ibn Abbas said to him, “I see that you seem sad and troubled.” The man replied, “Yes. O son of the uncle of the Messenger, I am indeed troubled in that I have an obligation to fulfill towards someone. I swear by the holiness of the inmate of the grave of this honoured resting place that I am not able to fulfill this obligation.” Ibn Abbas inquired, “Shall I intercede with that person on your behalf?” The man replied, “By all means, if you so wish.” Ibn Abbas put on his shoes and proceeded out from the mosque.  The man, seeing this, said, “Have you forgotten that you are in retreat to the mosque?” Tears filling his eyes, Ibn Abbas replied, “No, but the occasion is still fresh in my mind when I heard the esteemed inmate of this tomb say, ‘Whoever sets forth in the way of settling a necessary affair on behalf of his brother, that service shall be better for him than to perform retreat to the mosque for ten years; and whosoever performs retreat to the mosque for a day, God will spread three trenches between him and hellfire, the width of each trench being greater than the distance between heaven and earth.” [Baihaqi]
