Jami` at-Tirmidhi Book 44, Hadith 1
that the Messenger of Allah (ﷺ) said: "Indeed Allah has made a parable of the straight path: At the sides of the path there are walls with open doors, each door having a curtain. There is a caller at the head of the path calling, and a caller above it calling. And Allah invites to the abode of peace and guides whomever He wills to the straight path. The doors which are on the sides of the path are the Hudud (legal limitations) of Allah; no one breaches the Hudud of Allah except that curtain is lifted, and the one calling from above it is his Lord."
that the Messenger of Allah (ﷺ) said: "When you travel through fertile land, then give the camels their fill of the land, and when you travel through drought, then hasten while they are fresh, and when you camp late, then stay away from the road, for indeed it is the route of the beasts and the abode of poisonous vermin in the night."
that Jabir bin 'Abdullah Al-Ansari said: "One day the Messenger of Allah (ﷺ) came out to us and said: "While I was sleeping I had a vision as if Jibra'il was at my feet. One of them said to his companion: 'Make a parable for him' so he said: 'Listen so that your ears may hear. Hearken so that your heart may understand! The parable of you and your Ummah is but the parable of a king who conquers a land, then he constructs a house in it. Then he places a table-spread in it, then he sends a messenger to call the people to eat from it. Among them are those who answer the call of the messenger, and among them are those who forsake it. So Allah is the king and the land is Islam, and the house is Paradise, and you O Muhammad! You are the Messenger, so whoever responds to you he enters Islam, and whoever enters Islam he enters Paradise, and whoever enters Paradise, he shall eat of what is in it.'"
